Sorry to res this old thread, but I had this coin still sitting around and started wondering about it again, and I figured I shouldn't start a new thread for the same coin I'd previously posted. If I understand correctly, this couldn't be a doubled die, as the eye, being incuse, would actually be reduced in size on a doubled die, right? So then I got to wondering how this could be Machine Doubling, and at that, how it could be so displaced from the initial position without also showing MD elsewhere. Then I came across "ejection impact doubling" here: http://www.error-ref.com/ejection-impact-doubling/ I am wondering if anyone knows whether this is a likely explanation for what I'm seeing on the eye. The catch, however, is that the listing for EID says it only affected Sacagawea dollars for the year 2000, but it doesn't say if that's because there are no other known examples for other coins, or if that's because the cause was fixed after the 2000 Sacagawea coins. Anyone able to shed some light on this?
