I have a 1956 wheat penny and on the reverse, on the left wheat stalk (midways up) is a mark that looks like a D. What could this be? I'm not an expert on how these coins were minted, is there any way that the mint mark could have mistakenly placed on the reverse? it is about the same distance from the edge. Or is this just a flaw from a defective die? the coin is in unc condition so i know this didnt happen after the coin was made. Hope someone knows what it is.
Thanks,
Jonathan

How about a picture..??

I dont have a camera where I am. I'll post a picture later today. Is something like that possible though?

Ok what does this look like to you? the pic is on the attachment

If I see what you are talking about, then I suspect it is caused by a crack in the die used to strike the design.

i have around 27 of these yup just a die crack!!

I think I would call it a die chip.

Dockwalliper is correct. A die crack is a mere split in the metal. A die chip is a small piece of the die broken out. The term die break is often used for large die chips. Might as well toss them all in there, a broken die is where a die splits from one side all the way to the other.
