CentR Valued Member United States 139 Posts	Posted 01/04/2025 3:06 pm Would this be considered an RPM? This 1929-S Standing Liberty quarter appears to have a large S punched directly over a small s. I apologize for the lack of detail on the mintmark closeup image. I don't own the coin. It is at auction. Also of note, as Tanman points out, if it is an RPM, it is unattributed. From the relative size of the mintmarks I am wondering if the die was accidentally punched first with a Mercury dime mintmark, then corrected with the proper mintmark (approximate relative dimensions below). 1929-S Standing Liberty quarter Estimated Large S mintmark height: ~0.75 mm Estimated inner small S mintmark height: ~0.53 mm 1929-S Mercury dime Estimated mintmark height from PCGS image: ~59 mm Edited by CentR 01/04/2025 4:20 pm Report this Post to the Staff

Tanman2001 Pillar of the Community United States 4395 Posts	Posted 01/04/2025 3:28 pm Where are you getting the mintmark dimensions from? If I'm not mistaken, the same size mintmark punch was used for dimes and quarters that year. The photos isn't clear enough to really see if there is a RPM there, but I don't see anything that makes me think there is one. There is only one RPM known for 1929-S and this isn't it: http://www.varietyvista.com/08%20St...9SRPM001.htm Report this Post to the Staff
CentR Valued Member United States 139 Posts	Posted 01/04/2025 4:18 pm I did another estimate of the relative mint mark heights based on the diameters of a 1929 Standing Liberty quarter and a 1928 Mercury dime and the height in pixels of the coins and mint marks in the images. Mint mark height (mm)=(Coin diameter (pixels) x Mint mark (pixels) × coin diameter (mm). Report this Post to the Staff
