With examples fetching up to $95,000 at auction, this small silver coin might just be the jackpot hiding in your spare change, old coin albums, or inherited coin jars.
Whether you’re a seasoned collector or a curious beginner, knowing how to spot this rare dime could be financially life-changing. Here’s a simple guide to identifying the 1942/1 Mercury Dime, understanding why it’s valuable, and what you should do if you think you’ve found one.
Why Is the 1942/1 Mercury Dime So Valuable?
The 1942/1 Mercury Dime is an overdate error coin, meaning that the die used to strike the coin was first engraved with a “1941” date and then mistakenly re-engraved with “1942” on top of it. This mistake was never intended to be released into circulation but managed to slip past quality control.
There are two types of 1942/1 overdate dimes:
-
1942/1 (Philadelphia Mint)
-
1942/1-D (Denver Mint)
Both varieties are rare, but the Philadelphia version is slightly more valuable, especially in high-grade condition. The rarity, combined with historical significance and collector demand, drives prices sky-high.
How to Identify the 1942/1 Mercury Dime
Spotting a 1942/1 Mercury Dime requires close observation. Here’s what you need to look for:
🔍 Key Identification Features
| Feature | Description |
|---|---|
| Date | Look closely at the “2” in the date. You should see the bottom curve of a “1” peeking out underneath it. |
| Magnification | Use a 10x jeweler’s loupe or a digital microscope to inspect the date more clearly. |
| Mint Mark | For the 1942/1-D, check for a small “D” to the left of the torch on the reverse. No mint mark means it’s from Philadelphia. |
| Overall Condition | Even worn examples can be valuable, but uncirculated or high-grade coins command the highest prices. |

The value of the coin depends on its condition and whether it’s from the Philadelphia or Denver mint.
