In the world of modern U.S. coinage, very few circulation errors have achieved true landmark status. One that consistently stands above the rest is the 1982 No-P Roosevelt dime, a coin struck not in the distant past, but during the early 1980s, when millions of Americans were actively handling change every day.
That timing is crucial to its appeal. Unlike classic rarities that disappeared generations ago, the 1982 No-P dime entered everyday commerce. It passed through banks, amusement parks, vending machines, and cash drawers before collectors realized something was wrong. Today, it stands as the most important circulation-strike error in the Roosevelt dime series and one of the most significant modern Mint mistakes of the late 20th century.
Despite its modern origin, the coin possesses every trait collectors prize: a simple and understandable error, a direct link to Mint procedures, a discovery rooted in circulation, a limited but unknowable population, and a value range that continues to surprise even seasoned numismatists.
The Mintmark Change That Set the Stage
To understand why a missing mintmark on a 1982 dime matters, it’s necessary to look at what changed just two years earlier.
For most of U.S. Mint history, Philadelphia coins did not carry a mintmark. With few exceptions, most notably wartime nickels, Philadelphia production was identified by the absence of a letter, while Denver and San Francisco used “D” and “S.”
That changed in 1980, when the Mint began adding a “P” mintmark to all Philadelphia coins except cents. From that point forward, every circulating Philadelphia dime dated 1980 or later was supposed to carry a visible “P” above the date.
That policy shift is what makes the 1982 No-P dime so notable. After 1980, a mintmark-less Philadelphia dime should not exist at all.
How the No-P Error Happened
The 1982 No-P dime resulted from a single breakdown in the die-preparation process.
At the time, mintmarks were still added manually. Each working die received its mintmark punch by hand before the die was hardened and placed into service. In this case, one Philadelphia working die was never punched with the “P” mintmark but was nonetheless approved for use.
As a result, every dime struck from that die emerged without a mintmark. These coins looked perfectly normal to the casual observer, closely resembling pre-1980 Philadelphia dimes, except for the unmistakable 1982 date. Evidence strongly suggests the entire variety was produced from a single die, which explains both its scarcity and its consistency.
Once the die entered production, thousands of error dimes flowed directly into circulation.
Discovery in Sandusky, Ohio
The discovery story is one of the reasons the No-P dime remains so popular.
The first confirmed examples surfaced in late 1982, most notably in Sandusky, Ohio, near the popular amusement park Cedar Point. Employees, local businesses, and collectors noticed unusual 1982 dimes appearing in everyday change. The setting, an amusement park handling massive volumes of coinage, helped the error surface quickly.
As word spread, collectors across the Midwest began searching rolls of dimes, and additional examples were reported in surrounding regions. The geographic clustering supports the idea of a limited release rather than nationwide distribution.
How Rare Is the 1982 No-P Dime?
The U.S. Mint has never published production figures for the error, and because the coins circulated normally, an exact population will never be known.
However, submission data offers important insight. Based on certification totals at PCGS and NGC, the 1982 No-P dime ranks as the most-submitted clad Roosevelt dime variety, with the lone exception of the 1996-W dime. That comparison is telling. Unlike the 1996-W, which was a novelty coin never intended for circulation, the No-P dime is a genuine production error that entered commerce organically.
Collector consensus suggests that while thousands may exist, survival drops sharply in higher grades. This places the coin in a sweet spot: scarce enough to be respected, yet available enough to remain collectible.
Identifying a Genuine No-P Dime
Authenticating the 1982 No-P dime is straightforward when you know what to look for. The date must be 1982, no other year qualifies. A genuine example shows absolutely no trace of a mintmark above the date, with no outline, shadow, tooling marks, or disturbed metal. The coin must also match the normal die characteristics of 1982 Philadelphia dimes, including proper portrait detail and correct spacing.
Altered coins, where the “P” has been scratched away, are common but easy to detect under magnification. Wear alone will not completely remove a mintmark in a natural way.
Strong vs. Weak No-P Dimes
Most numismatic references recognize two strike classes of the 1982 No-P dime: Strong and Weak.
These terms do not describe the mintmark, both lack it entirely, but rather the completeness of the strike. Strong No-P dimes show crisp design details, particularly around the rims and lettering, closely matching a fully struck normal issue. Weak examples exhibit flattened outer details, with portions of the design nearly obliterated.
While both are legitimate varieties, many collectors consider the Strong No-P to be the more desirable and numismatically interesting of the two. Collecting both is a personal choice, but market demand tends to favor sharply struck examples.
Market Values and Collector Demand
Values for the 1982 No-P dime vary widely by condition.
Circulated examples in Extra Fine condition typically trade around $30, making them accessible entry points for collectors. Uncirculated pieces bring substantially more. A Mint State example in Gem condition or better often commands $300 or more, with premiums rising quickly for coins certified in the upper Mint State range.
As with most modern errors, condition rarity is the primary driver of price. High-grade, well-struck examples are significantly scarcer than the raw population numbers suggest.
Why the 1982 No-P Dime Still Matters
More than forty years after its discovery, the 1982 No-P Roosevelt dime remains a cornerstone of modern U.S. numismatics. It demonstrates how a single overlooked step in Mint procedure can create a lasting rarity. It shows that meaningful errors did not end with the silver era. And it continues to fuel the enduring appeal of searching everyday change.
Perhaps most importantly, it proves that modern coins can still tell compelling stories, stories rooted not in vaults or proof sets, but in real circulation.
A Small Coin with Lasting Significance
The 1982 No-P Roosevelt dime doesn’t rely on mystery or speculation. Its error is clear, its history well documented, and its desirability firmly established. Whether found in a coin roll, acquired for a Roosevelt dime set, or pursued as a standalone error, it remains one of the most important modern U.S. coins ever struck.
In a hobby built on history, the No-P dime is a reminder that history sometimes happens quietly, one missing letter at a time.
I will looking. Never knew about this.
A production error is very unusual. I’m on the lookout and hoping to find one. If you hear a cheer from my home in Arizona, you will know that my search was successful.
I’ve been looking for one of these.
Great article!!! I acquired one of these dimes many years ago at a coin show.
I keep hoping to find one. Hopefully soon.
You can’t help but wonder how errors like this escape the Mint. Was this a case of an overlooked omission due to the small size of the coin? Was it something intentional on the part of a Mint employee (like the modern “Extra V” penny)? Or was it simply a classic Friday afternoon oops? Guess we’ll never know. Fun stuff, either way.
I always look at my spare change. If i see something that looks unusual, I research. You never know what you will find.
Im still looking. Thank you for letting us know about this. Always great articles.
Nice I will keep an eye out for these.
Do these have the same value as a Merc Dime when it comes to M+D BJ buying power?
I am always on the hunt for errors
Very interesting info

This is a piece of history!! It’s cool to see we still make mistakes in the process to give the average Joe a chance of finding something incredible.
checking mint marks now.
I’ve been searching in my change since the 80’s. No luck on this one. Good luck to all!

Something I’ll be searching for in my coin stash in the cold couple of months coming up.
Interesting information about a random missing mintmark.
I noted in an above comment that I was going to search my small pot of Roosevelt dimes for a 1982, no mint mark. I did so. As luck would have it I did NOT have one.
But somehow, some way an 1892 Barber made its way in there. I never had one before.
Very rough shape. But an exciting find to me.
Thanks for the incentive to check.!
Back to searching now.. :)
Good article with lots of background information.
Would be nice to find one.
Well how cool is that. Never heard about the missing P. Thanks.
Have looked for these for many years, but still no luck so far!
still looking haven’t found one
No luck yet, But I keep searching.
Think I’ll start watching my dimes more closely. Never knew this 1982 P dime had this issue.
I really do like raking in the knowledge about coins. The more I learn, the more that might stick with me.
It’s now been 80 years of the FDR dime. Isn’t it time for a new design?
Hopefully i can find one roll hunting
I know it is unrelated but the 2026 dime is beautiful and cannot wait. Article is a good read but looking forward what is to come.
I agree with George, something else to look for.
I have never heard about this.
Non silver dimes are not as magical but still collectible at times.
I’m always looking for treasures in my change.
The 1982 dime no P mark will be added to the list.
Great and informative article, need to start looking for one!
Haven’t found one but I’ll keep searching….
I’ll be looking for one of these. Very interesting story.
