Sandon Posted February 2 Share Posted February 2 Welcome to the NGC chat board. First of all, I think you mean to suggest the coin is an S over D, as the coin is clearly a proof struck at the San Francisco mint with the normal, blobby "S" mintmark used at that time being the predominant image. More importantly, the coin does not show any evidence of a "D" underlying the "S", only a small defect in the punch used to enter the mintmark into the die that appears as a small, raised line in the upper loop of the "S". (The "S" punches had been used for many years and had deteriorated, resulting in their finally being replaced in 1979, with the new punch first appearing on 1979-S "type 2" proof coins.) No overmintmark variety is known to exist for bicentennial quarters. Here for comparison is an NGC VarietyPlus photo of the mintmark on a 1955-D, D over S nickel (FS-501). The "D" is the predominant image, and you can clearly see remnants of the underlying and partly effaced "S" above, to the left of, and within the "D".

EagleRJO Posted February 2 Share Posted February 2 I think you are getting faked out by using the scope, with that lighting and reflections giving the appearance of something else. Looking at the second photo does not give the same indications as your first magnified scope picture. If you just looked at it with a 10x loupe or glass with normal lighting I think it wouldn't look the same. And as Sandon noted there are no listed OMMs for this 1976 quarter, so discovering a new one while technically possible, isn't very likely.

Sandon Posted February 2 Share Posted February 2 Please post inquiries about additional coins as separate topics. Please also provide cropped images of the entirety of each side of each coin. Your 1964-D nickel is definitely not a D over S. It may be a faintly repunched "D" mintmark. It doesn't match either of the varieties listed on NGC VarietyPlus. See Jefferson Five Cents (1938-Date) | VarietyPlus® | NGC (ngccoin.com). (The first variety, FS-501, has no photos on VarietyPlus, but I checked it against photos in The Cherrypickers' Guide to Rare Die Varieties.) You can compare your coin to the repunched mintmark (RPM) listings on varietyvista.com and doubleddie.com to see if you can find a match.

Try to NOT look for particular things, like OMM’s. You’ll talk yourself into all kinds of things. Link to comment Share on other sites More sharing options...
