New Hampshire has been stamping plates onto its vehicles since 1905, and the metal has changed shape, color and wording many times in the years between. The history of New Hampshire license plates runs from a porcelain tag issued by the state before the First World War to the pale blue reflective base mounted on cars today. Every redesign on that timeline answered a practical problem, from a fragile face that chipped under a knock to a serial system that ran out of numbers.
This page follows the New Hampshire license plate history in order, from the first 1905 plate through the county codes that ran to 1979 and on to the current base that arrived in January 1999. It covers the 1926 debut of the Old Man of the Mountain, the scenic designs of the 1970s, and what old New Hampshire license plates are worth to a collector who buys and sells them today. The rules for registering an antique vehicle sit in a separate section of this site, and this page stays with the years rather than the paperwork.
How to Date a New Hampshire Plate
A New Hampshire plate can be placed in time by a handful of features on its face. The wording, the color of the characters, the serial pattern and the material all changed at known points, and a close look at those four things narrows a plate to a short span of years. Collectors use the same clues the state used when it ordered a redesign, and the order of those changes is the order of the sections below.
- Check the material first: porcelain enamel through the 1910s, then flat pressed metal
- Read the motto, since LIVE FREE OR DIE reaches regular passenger plates in 1971
- Look for the Old Man of the Mountain, which appears on a plate from 1926
- Count the serial, where a two-letter prefix points to the county years from 1949 to 1979
- Test the shine, since reflective sheeting arrives in the late 1970s
- Note the color, as white with green characters runs until January 1999
- Look for a portrait set inside a circle, which marks one short run in the 1990s
- Weigh the tag, since an early porcelain face is heavier and far more brittle than steel
Those clues stack in a fixed order. A white plate with green characters and a two-letter prefix belongs to the county-code years. A pale blue plate with the Old Man and a seven-digit serial sits on the current base. A porcelain tag with a plain number sits at the very start. When two features seem to disagree, the material and the serial pattern decide, since the state reused colors and slogans across more than one design.
The First Plates 1905 to 1929
New Hampshire issued its first license plates on 4 April 1905, and the earliest tags were made of porcelain rather than the pressed metal a driver knows today. The state handed a number to each vehicle and expected the owner to mount it at the back. For a few years before 1905, motorists had built their own tags or carried a maker’s plate, which left no single system in place until the state stepped in and took charge of the number.
The 1905 porcelain issue
The first New Hampshire plates were sheets of metal coated in porcelain enamel, a finish that gave the face a glossy white surface with a dark number. Porcelain held its color well in weather, yet it cracked under a knock and rusted from the first chip. The state baked the coating onto the steel, so the two layers pulled against each other in cold weather and the enamel flaked at the edges. Few of those 1905 tags survive, and a genuine early porcelain plate is one of the hardest pieces of New Hampshire material to find. The 1905 plate carried a plain serial with no county letters and no artwork. That bare face is the cleanest marker of the earliest years, since every later change added something to the plate. A collector who handles a porcelain New Hampshire 1905 plate is holding the point where the state replaced private tags with one official series.
Flat metal replaces porcelain
The state moved to flat metal in the years that followed, and the pressed steel tag became the standard. A flat plate could be stamped in volume, painted in one pass and reissued each year without the cracking that ruined the porcelain faces. The surface took a plain painted number at first, then a light finish that reflected a little more of a headlight. That change settled the basic shape of the New Hampshire plate: a rectangle of metal with rounded corners, close to the 12 inch by 6 inch size still used on the road. Flat metal made repairs simple. A bent steel tag could be straightened, and a faded number could be repainted, where a chipped porcelain face could not be saved at all. That durability is why plates from the 1910s and 1920s outnumber the porcelain years in every collection.
State-issued tags take over
Before the state issued plates, an owner supplied the tag and the number that came with a car was its own. Once the state printed the tag, the plate number attached to the vehicle and had to be accounted for when the car changed hands. The 1920s brought the annual reissue, a fresh plate each year, which is why surviving tags from that decade often carry a year marking on the face or along an edge. A collector places an early New Hampshire plate more often by that year marking than by the serial, and a tag with no year needs a closer look. By 1929 the state had a working system: a stamped metal tag, a year mark, a state name and a number that moved with the vehicle. Everything that followed built on that base, and the next change gave the plate its most lasting image.
The Old Man Arrives 1926
The Old Man of the Mountain first appeared on a New Hampshire plate in 1926, and that single change altered how the state presented itself on the road. The rocky profile at Franconia Notch had become a state emblem long before a designer put it on a tag, and the 1926 plate carried the face as a mark of place. A 1926 New Hampshire license plate is the tag collectors ask for first when they build a New Hampshire run, since it opens the long line of Old Man designs. The face returned in later issues and stays on the plate today as a state symbol. The 1926 tag is a landmark in New Hampshire license plate history for a second reason. It sits at the point where the state stopped treating the plate as a bare number and started treating it as a small piece of official art. From that year the face of the plate carried a state image, a direction the later scenic and commemorative designs followed. Another section of this site covers antique plates and the year-of-manufacture route for putting an older plate onto a registered vehicle, and the history here stays with the design itself. Plates of the 1920s were reissued each year, so a 1926 tag belongs to a single registration year rather than a standing series. That makes any survivor a dated object, easy to place and hard to confuse with a later Old Man plate. A 1926 face carries the profile in a plain rendering, far from the pale sky field and Cannon Mountain backdrop that frame the symbol on the current base, and the difference between the two is the clearest way to sort an early tag from a modern one.
County Codes, 1949 to 1979
From 1949 to 1979 New Hampshire sorted its passenger plates by county, and the first letters of the serial told a driver where the car came from. Each county drew a block of two-letter prefixes, so a plate began BA or CA or EA and that block named the county. County codes gave the state a way to spread serial numbers and gave local offices a simple rule for issuing them. New Hampshire license plate county codes lasted three decades and stand as the clearest map of the state a plate has ever carried.
| County | Letter block | Notes |
|---|---|---|
| Belknap | BA–BZ | One block covered the county |
| Carroll | CA–CZ | One block covered the county |
| Cheshire | EA–EZ | One block covered the county |
| Coös | OA–OZ | The northern county |
| Grafton | GA–GZ | One block covered the county |
| Hillsborough | HA–HZ, IA–IZ, JA–JZ, LA–LZ | The largest county, four blocks in all |
| Merrimack | MA–MZ, NA–NZ | A second block added later |
| Rockingham | RA–RZ, KA–KZ, PA–PZ | Three blocks in all |
| Strafford | FA–FZ, DA–DZ | A second block added later |
| Sullivan | SA–SZ | One block covered the county |
A county plate reads as two letters and then a run of digits, with the first letter naming the county and the second stepping through the alphabet as numbers were used up. A car registered in Hillsborough began with HA, and a car registered in Sullivan began with SA. Two neighbors could hold plates with the same digits and a different first letter, and the letters told them apart at a glance. The system ran until 1979, when the state retired the county prefix and moved to a single statewide series.
How the two-letter system worked
The first letter of the pair named the county and the second ran through the alphabet as the county used up numbers. Belknap began at BA and worked toward BZ, Carroll began at CA and worked toward CZ, and the pattern held down the list. When a county filled its first block, the state opened another block for it, which is why a few counties own more than one starting letter. The serial after the two letters carried the count, so the plate read as two letters and then digits, year by year, until 1979 closed the series.
Why Hillsborough and Rockingham picked up extra blocks
Hillsborough and Rockingham hold the largest share of New Hampshire’s population, and their car counts ran through a single letter block long before 1979 arrived. Hillsborough took HA through HZ first, then added LA through LZ, IA through IZ and JA through JZ to keep issuing plates. Rockingham took RA through RZ, then added KA through KZ and PA through PZ. Merrimack drew MA through MZ and later NA through NZ, since it, too, ran past one block. Strafford ran FA through FZ and picked up DA through DZ. Those extra blocks are the fingerprints of a growing state. A plate with a KA or a JA prefix dates to the later county years, since the state reached for additional letters only after the first blocks filled. A county with a single block, such as Belknap or Sullivan, never needed a second pair, and a tag from either of them stays easy to date. The last county-code plates rolled out in 1979, and the series closed for good.
From White to Green 1979 to 1998
The county codes ended in 1979, and the plate that replaced them set the look most drivers still picture when they think of an old New Hampshire tag. The state dropped the two-letter county prefix and moved to a white face with dark green characters and a clean serial. That plate carried Live Free or Die, the state motto, across the top and the state name along the bottom, in the green that would stay on New Hampshire metal for two decades.
The switch to a reflective plate
Reflective sheeting arrived on the New Hampshire plate around the time the county codes closed. A retroreflective face bounces a headlight back to the driver, which keeps the characters readable at night and in rain. The sheeting let the state print a full graphic on the face rather than paint a plain number, and it made the tag cheaper to produce in volume. That change turned the 1979 New Hampshire license plate into a marker, since the tag moved from a flat field of color to a surface that could hold a picture.
The ABC-123 serial
The new serial ran as three letters followed by three digits, an ABC-123 pattern that gave the state far more combinations than the county blocks had allowed. Three letters and three digits produce millions of plates without a county prefix, which is why the format carried the state for the rest of the century. A New Hampshire license plate 1979 issue with that layout sits at the head of the run, and the serial tells the story of a state that had outgrown its local code. The move away from the county prefix meant a plate no longer named a place. Two cars from opposite ends of the state could hold serials that differed by a single letter, and the state gained room to reissue numbers for a full generation. The scenic designs of the 1990s then sat on top of that statewide series rather than on a county block.
The Old Man in a circle
In the 1990s the state tried an Old Man portrait set inside a circle, a short run that stands apart from the rest of the series. The circular framing drew the eye to the profile and gave the plate a badge-like center. The design did not last, and the plate returned to the wider sky scene, yet the circle run is one of the easiest markers to date, since no other New Hampshire passenger plate carries it. A collector who finds a plate with that circular portrait can place it in that one window without checking a year code.
The Current Base Arrives January 1999
The current New Hampshire base arrived in January 1999 and has stayed on the road since. It keeps the green characters of the 1979 design and places them on a pale blue sky field, with the Old Man of the Mountain and Cannon Mountain behind the serial. LIVE FREE OR DIE runs across the top and New HAMPSHIRE along the bottom, the cursive New sitting above a serif HAMPSHIRE. The tag is 12 inches by 6 inches of reflective aluminium, mounted front and rear on cars, trucks and commercial vehicles.

The Old Man Collapses May 2003
The Old Man of the Mountain collapsed in May 2003, and the profile that had sat on New Hampshire plates since 1926 was gone from the cliff. The state chose to keep the symbol on the plate, and the face stays on the current base as a state emblem rather than a portrait of a standing rock. Drivers who held an older tag with the same face suddenly carried a memorial as much as a plate, and the image took on a weight it never had in the years the rock still stood. The collapse did not force a redesign. The plate on the road in June 2003 looked the same in July, which makes the year a clean marker for a different reason: it separates the living mountain from the remembered one. The state kept the symbol in official use, and the plate carried that decision forward into every later issue on the same base. For a collector, a plate made before May 2003 carries a face drawn from a mountain that no longer stands, and that fact raised interest in the earlier Old Man issues. The 1926 plate and the circle run of the 1990s both drew more attention after the collapse. The design on the metal never changed in 2003, so the year matters to the story rather than to the plate’s appearance.
What an Old Plate Is Worth
Value in old New Hampshire license plates follows condition, age and the number on the face, the same three things a buyer weighs on any plate. A clean 1926 tag or an early porcelain face sits at the top, and a common 1980s passenger plate sits near the bottom even in good shape. The state does not sell or value old plates, so the figures come from collectors, swap meets and online listings rather than any official table. That means a price moves with the market and with the two people at the table.
- Age first: the 1905 porcelain and the 1926 Old Man plate lead the market
- Condition second: bends, rust and chipped enamel cut value hard
- Low numbers and short serials add a premium on any year
- A matching pair of plates is worth more than a single tag
- County-code plates from 1949 to 1979 sit in the middle range
- A plate still on a car in regular use is not a collectible yet
New Hampshire license plates for sale turn up at tag shows, in antique shops and in online listings, and a buyer should check the New Hampshire License Plate rules before mounting an old tag on a car. The year-of-manufacture route and the antique registration rules sit in another section of this site, and this page stays with what the metal itself is worth. A vintage New Hampshire plate that still shows its original paint and straight edges holds the most money, and a bent, repainted example from the same year can be worth a fraction of a clean one.
Frequently Asked Questions
The questions drivers and collectors ask most often about the history of New Hampshire license plates.
When did New Hampshire issue its first license plate?
New Hampshire issued its first plates on 4 April 1905. Those earliest tags were porcelain over metal, and the enamel cracks easily, so few of them have survived to today.
When did the Old Man of the Mountain first appear on a plate?
The Old Man of the Mountain first appeared on a New Hampshire plate in 1926. The symbol stayed in the state’s plate designs and still frames the current base, even after the cliff face collapsed in May 2003.
What were the New Hampshire county codes?
From 1949 to 1979 the first two letters of a passenger serial named the county. Belknap ran BA through BZ and Carroll CA through CZ, and the larger counties, Hillsborough and Rockingham, drew several blocks before the system closed in 1979.
When did LIVE FREE OR DIE reach the plate?
The motto reached regular passenger plates in 1971. It has stayed on the plate since, across the white and green design of the late 1970s and the pale blue base that arrived in January 1999.
Is an old New Hampshire plate worth money?
Some are. A 1905 porcelain tag, a 1926 Old Man plate and low-number serials carry the most interest, and condition decides much of the rest. A common later passenger plate holds little value.
