Yes Hello. I was going through my late Grandmother's coin album and this was among other errors on the first sleeve, top row. It's a 1956 Quarter with no Mint mark but as you can see the Reverse looks like something else was struck onto it between 8 and 4 O'Clock. The obverse is plain to see with the I, B E and R looking as if it were wiped away but i'm sure there is a reason why it looks like that. Can anyone share their expertise please? My novice opinion, or what i see: If you turn the Reverse face on it's side to the left I see '5' and '4' just underneath that , with the 4 being slightly clipped by the edge of the coin. I just find that weird considering this is a '56? I can't get he greatest shots because of the cellophane but if you would like more let me know.
Easier to see with full-size pictures... The flattening you see on the obverse is due to someone putting another object like a coin on the reverse and striking it with a hammer. Often referred to as PMD (Post Minting damage) Welcome to CT
Sorry, but everything you see is damage. Not an error of any kind. It's still worth silver melt value.
