What if a simple dime in your pocket was worth hundreds of dollars?
While most 1982 Roosevelt dimes are only worth face value, a rare minting mistake from the Philadelphia Mint has turned some into $200–$500 collector treasures. This error is known as the 1982 “No P” Dime, and it remains one of the most popular modern U.S. coin errors searched by collectors today.
Below is a step-by-step guide explaining why this dime is valuable, how to identify it, and what to do if you find one.
Step 1: Why the 1982 “No P” Dime Is Special
The year 1982 marked a major change in U.S. coin production.
For the first time ever, the Philadelphia Mint began placing a “P” mint mark on dimes.
Mint Locations in 1982:
• 
Philadelphia (P) – circulation coins
• Denver (D) – circulation coins
• San Francisco (S) – proof coins only
The Error:
A small number of Philadelphia dimes were struck without the new “P” mint mark, creating the now-famous 1982 No Mint Mark Dime.
Step 2: How Much Is a 1982 No P Dime Worth?
Value depends heavily on condition and certification.
Current Market Values (2025)
| Condition | Estimated Value |
|---|---|
| Circulated |  $50 – $150 |
| Uncirculated | $150 – $300+ |
| Graded MS65+ | $200 – $500+ |
Verified Sales:
• $210 – PCGS MS65 (eBay, 2023)
• $450 – NGC MS67 (Heritage Auctions, 2022)
Certified coins consistently sell for more than raw examples.
Step 3: How to Identify a Genuine 1982 “No P” Dime
Follow this checklist carefully before celebrating:
Check above the date – No mint mark at all
Use a 10× loupe – Ensure it wasn’t worn off
Compare side-by-side – Look at a normal 1982-D dime
Smooth blank area – No scratches or filing marks
Important: Faint mint marks can be deceptive under poor lighting. Always inspect under bright light.
Step 4: Avoid Fake or Altered Dimes
Due to rising prices, altered coins are common.
Filed-off mint marks (visible tool scratches)
Polished or cleaned coins (reduced value)
Incorrect surfaces near the date
Best practice:
Coins graded by PCGS or NGC sell for the highest prices.
Uncertified coins rarely exceed $200.
Step 5: What to Do If You Find One
If you believe you’ve found a real 1982 No P Dime:
Do not clean it
Handle by the edges only
Store in a coin flip or capsule
Take clear photos (front and date area)
Get It Graded:
• PCGS or NGC
• Typical cost: $30–$50
• Authentication + higher resale value
Step 6: How to Sell Your 1982 No Mint Mark Dime
Best Selling Options:
eBay – Use sharp macro photos
Coin forums – CoinTalk, Reddit r/Coins4Sale
Local coin shops – Faster sale, lower payout
Expect local dealers to offer 30–50% less than auction prices.
Step 7: Why This Error Happened
During the 1982 transition, the Philadelphia Mint was adjusting production methods.
Some dies were used without the new “P” mint mark, allowing error coins to escape into circulation.
Today, these overlooked dimes are among the most famous modern U.S. mint errors — and they are still being found.
Final Thought: Check Your Change
Every jar of spare change has potential.
That ordinary dime could be:
A historic minting mistake
A collector favorite
Worth hundreds of dollars
Don’t overlook it.
