Miss placed MM's. I will be honest, I haven't searched much further than Coneca 1-67 of their RPM's. Does this look like one. Or is this some dropped element that etched it's way onto the Die face? There is also a little die chip marker on the O of one.
Sometimes it is just diving into key words on the internet. It looks like a D in hand with better details under a loupe. The D is fully formed. It is just a little bit larger than a MM.
IMHO, since MMs were hand punched at that time (1960), there is bound to be movement of the mint mark, but it might not result in a rpm. https://doubleddie.com/58243.html
It is, as you say, slightly bigger than the original MM, but it is also smaller and wrong shape to be a dropped D from God. Planchet flaw that was not struck out?
Thanks ya'll I am gonna take another look at this one a little later after I wake up. I will let you know what I have come up with.
It is actually the same shape and size as the D from God. I will try and get some better photos. It would be beneficial of I had a stacking program.
Well I also said dropped element. The thing is that it doesn't look like a dropped element There is a very fine raised outline of a D.
Does anyone know how to use Gimp? I would download the program but my computer is old and scared that it will slow my system down even more than it is right now. @justafarmer if it is not too much trouble can you check the image against the size of the D from God and the MM?
It is the compacted grease and debris in the incused part which falls out and is then subsequently struck into the coin wherever it landed.
@robec For a dropped element to have been struck that many times that it changed and altered the die face is uncommon. I am still having trouble identifying this coin. I have some photos that I still need to crop. That say it is raised on the coin. I will do that soon. So, that there isn't any confusion as to what I see in hand VS the provided photos so far.
I am having a hard time showing the straight upright to the D, but it is also raised. Just nearly horizontal.
