While both errors are relatively equal in value in Circulated grades, in Choice condition the Philadelphia error carries a significantly higher premium than does the Denver error. On both errors doubling of the “4” in the date is reasonably discernable as well, and in the latter instance is the most discernable feature evidenced. The Philadelphia Mint overdate is the more distinct and scarcer of the errors, with the “1” closing the loop on the “2.” On the Denver Mint overdate, the “1” is barely discernible. An MS68 1943 Denver dime without the full band designation is worth 1,100. A Denver mint mark does, however, offer a premium at some grades. That rises to 11 for an MS60 example, and to 15 for a coin at the same grade with a full band. An unknown number of dimes were struck with the production dies before the error was detected. A 1943 Denver dime graded XF45 is worth about 5. The result was working dies with a “2” sunk over the “1” of the date. Both were produced when production dies in the preparation process were first sunk with a 1941-dated hub die and then, by accident, finished with 1942 hub dies. Q: Can you explain what is meant by a 1942/41 dime? Is it a dime struck with a dual date?Ī: Two major “overdate” Mint errors exist for 1942, one from the Philadelphia Mint and one from the Denver Mint.
