Here's the Double Tail and Back Bison. I pretty sure this is strike doubling (machine doubling). Right Mike? Still a very noticeable error and on a very cool and popular coin. So, Mike (even though I think this is strike doubling) I have this (exactly the same) on over a hundred coins. My question is, can the rattling of the dies produce the exact effect on hundreds of coins? Also, Does ANACS identify this type of error? Thanks.
