One of the most interesting varieties of United States gold coinage is the many overdated issues that exist. Some are very rare and others are common; some are well-known and some are very obscure. But all share a common trait: a high “coolness factor” that makes them desirable with collectors. What are overdates and how can the collector of United States gold coins focus on these issues?

An “overdated” coin is one on which two dates are present. A famous example is the 1942/1 dime. An overdate occurs when one of more digits from the current year is punched into an older working die. Overdates are often intentional creations and they may exist for a number of reasons.

In the early years of the US Mint, steel to make dies was scarce and funds were scarcer. The Mint operated on a shoestring budget and if any dies were leftover at the end of the year, there was good reason to reuse them. There are many overdates from the 1790’s and early 1800’s and many were probably caused by economic reasons.

Quality control at the Mint during the early years was often lax and some overdates appear to have been produced by accident. These accidents occurred when an engraver inadvertently employed a date punch that was not consistent with the die he was working on. This appears to be the case with some of the overdated coins produced during the 1830’s and 1840’s.

Let’s look at some of the more interesting overdates that occur on Liberty Head gold coins. We’ll save overdated early U.S. gold coins for another time as the list and scope of these is very comprehensive.

Gold Dollars:

There are no gold dollars that were overdated. It is interesting to note that there are very few varieties of note in this entire denomination. The branch mints, where one would have expected an overdate or two to have occurred, never produced one in this denomination.

Quarter Eagles:

The Philadelphia, Charlotte and Dahlonega issues from 1839 have been called 1839/8 overdates in the past but this is incorrect. The only genuine overdate for the Liberty Head type is the 1862/1. This is a clearly visible overdate that was probably caused by the stress involved with producing gold coinage during the most intense year of the Civil War. It was once believed to be extremely rare but now is only regarded as very scarce. In higher grades, the 1862/1 is very rare. I have personally seen two or three in Uncirculated including a PCGS MS62 that was the best of these. (more…)
