Do the serifs or points of the D have splits ?
In my opinion, If you are concentrating on the area south or just below the mintmark, that sort of look is around the base of the 9 and 5 of the date. More than likely that is not a RPM.
Good websites to use for RPMs and doubled dies to find a match are:

Anthony Dollars SacajaweaDollars PresidentialDollars Bullion Commemoratives Mint Medals Coppers &Flying Eagles Indian Cents Half Dime Shield Nickels Liberty HeadNickels
Die varieties such as doubled dies, Repunched mint marks (RPMs), Over Mint Marks (OMMs), Repunched Dates, Overdates, coin design varieties, as well as regular coins and error coins.

A lot of different things can happen on the surface of the die when the MM is punched into it. This sort of "ghost" MM is common in this period, and can mimic an RPM. Take a look at it from different angles to see what is happening. Is the area in question raised or incuse? Does it have the exact shape of that part of a MM punch?

It just needs lighting on the split serifs. CONECA might consider just split serifs a minor RPM. As these RPMs become less available, CONECA might list them, if they haven't already.
Http://coppercoins.com might be the best place to find a match. It is imperative to realize where the mintmark is positioned on the coin. Before 1989, the mint marks were hammered into each working die. That meant there are subtle differences in location for each mintmark, but matches can be had. That lead to some human errors and RPMs were born. RPMs were eliminated in the early 1990s when the US Mint decided to add the mint mark to the design of the coin.
The attributors who have documented all the currently have found will offer direct, head on photos of the year and mintmark. This helps other attributors and collectors to identify which RPM they might have. Some may go as far as creating an overlay which cements the attribution if the position of the mint mark is right on.Last edited by MintErrors; 02-22-2024, 08:55 PM.Gary Kozera
