Hi,
I know I posted under this one but I don't know where the post went:-)
Anyway, Staring in 1990, the mintmarks were a part of the die and were no longer punched in by hand. That makes a D over S or any other overmintmark an impossibility.
This one is just showing an interestingly shaped bit of corrosion.
Thanks,
Bill

nice eye. Unfortunately I will have to agree with foundinrolls. Since they were done by hand, the probability of it being D/S is very very low. But, you never know...

Foundinrolls is absolutely correct. This being a D/S is impossible...NOT improbable.

you guy still forget that the San Francisco mint still hand stamp the mint mark if they did this the other way it will be in large letter S.they use the plilly coin dies to stamp into.

So if I have this right, Lincoln cents from 1990 onward have their mintmarks included on the galvano? I can see how that would eliminate the possibility of a D/S, especially since nobody in the Denver mint would be using mintmark punches--ever. Denver would have its master hub for 1992- D from which all master dies, working hubs and dies would be based? That pretty much eliminates this possibility, doesn't it?  Edited by KurtS

The scenario of an S punch from a proof coin is also impossible. Besides, the spot of corrosion even if it were an S, which is still impossible, is to small to be any letter. It's a spot o' rot...nothing more than that.
Thanks,
Bill

Actually 'galvanos' were retired years before this change.
The mintmark was included as a part of the 15x size epoxy mold of the original design which was in-turn used on the reduction lathe to achieve the coin-sized master hub. In the case of cents, the mintmark was ground-off of a D mint or S mint casting to be used for Philadelphia hubs (no-mintmark).
One of the US Mint videos shows this process in action with a 1997 quarter cast...a whitish colored (epoxy) dinner-plate sized quarter obverse that exhibited a 'P' mintmark.

But still my response to this thread remains the same....impossible for an OMM to happen on non-punched dies.

Thanks Chuck for that info! I had forgotten and used the older term. In any case, I have the general concept.  |
