In 1982, a small batch of Roosevelt dimes struck at the Philadelphia Mint was accidentally released without the “P” mint mark, making them one of the most sought‑after modern mint errors. These are business‑strike coins, not special proof or collector issues.
How Did the Error Occur?
During production, early dies meant for 1982 circulation dimes were prematurely used before the “P” mint mark was punched in. Mint officials adjusted striking pressure, creating strong and weak varieties of the error.
Where & When Were They Found?
- December 1982: First examples discovered in Sandusky, Ohio.
- Given out at Cedar Point as everyday change.
- August 1983: More found in Pittsburgh. Later discoveries in Boston, traced back to the Cleveland Federal Reserve.
According to coin experts, approximately 8,000–10,000 coins were initially found, with later estimates suggesting up to 150,000 released into circulation.
Varieties: Strong vs. Weak Strikes
- Strong strike: Highly defined, sharp details—around 47–48 coins fit a standard roll.
- Weak strike: Softer detail—around 50–51 coins per roll .
Experts suspect the weak strike dies were used first, followed by higher-pressure strong strikes until wear forced die retirement.
How Rare Are They Today?
Despite initial estimates, many are still found in circulation. However, uncirculated or gem condition specimens are very rare. Their value is a combination of condition and strike quality.
Market Value & Recent Sales
The value varies widely depending on condition, strike quality, and grading:
Condition / Strike | Estimated Value |
---|---|
Weak strike, MS‑60 | ~$50 |
Strong strike, MS‑60 | ~$100 |
Weak strike, MS‑68 | Up to $1,000 |
Strong strike, MS‑68 | Up to $2,500 |
Circulated (VF–AU) | Typically <$100 |
Superb gem examples | As high as $475,000+ |
- Strong strike MS‑68 examples may command $2,500.
- Most circulated error dimes are worth under $100.
- A recent find was valued at $475,000, though details are still emerging .
How to Spot One in Your Pocket
- Check the obverse above the date: 1982 dimes should have a “P” mint mark. If absent, it’s a candidate error.
- Evaluate the strike: Sharp detail = strong strike; softer detail = weak strike.
- Condition matters: Uncirculated (MS) coins will be far more valuable.
- Professional grading (e.g., PCGS, NGC) confirms authenticity and ensures market trust.
Why It Matters
- It’s the first business‑strike dime accidentally released without a mint mark.
- Offers a modern “Easter egg” for collectors and roll-hunters.
- Value spikes significantly for gem-quality specimens.
- The story reflects historical production oversight and human error at the Mint.

The 1982 No-Mint-Mark Roosevelt Dime is a fascinating and unique modern mint error that shows how small production mistakes can have massive collector appeal.
With two distinct strike variations—weak and strong—and a discovery story rooted in Ohio’s Cedar Point and the Cleveland Fed, these dimes remain treasure troves for roll-hunters everywhere.
While many in circulation remain modestly priced, gem-quality, strong-strike examples have sold for tens of thousands—potentially even reaching the six-figure mark.
Next time you’re counting change, look for that missing “P”: you might just find your own piece of numismatic history.
FAQs
Q1: Can any 1982 dime without a mint mark be valuable?
Yes, but condition and strike quality matter. Circulated error coins are typically under $100. High-grade, strong-strike examples (MS‑65 or higher) can reach thousands of dollars.
Q2: What is the difference between strong and weak strike?
Strong-strike coins exhibit sharp, crisp design elements. Weak-strike pieces appear softer and less defined. Strong-strike errors are significantly more valuable.
Q3: How can I confirm if a dime is genuine?
Have it graded by a reputable service like PCGS or NGC. Grading ensures authenticity and assigns condition and strike quality, which are critical for valuation.
