rzage the last coin of the ones you posted: If an avid shooter found that on the ground or on a table, he would think it was the jacketing and lead of a bullet that had struck a steel plate! He would have probably tossed it in the trash or lead bin. That's quite amazing.
The four coins depicted above are a mixture of die caps and capped die strikes. The former are considerably rarer and more valuable than the latter.
Here is a neat die cap from Argentina. The slab has an additional error on it. The coin is a 10 Centavos. You can see the ghost image of "10 Centavos" on the coin. It is the same metal & expanded to the approximate size of an Argentina 50 Centavo. NGC indicated 50 Centavos on the slab in error.
That is a cool coin to, thanks Collect89!!!!! Ya being an avid shooter myself, it really does look that way.
I'm gonna say the cent that is the subject of this topic looks like it was hit with a small ball peen hammer.
