Quote:CoinMonster777: I see you've recently posted a lot of suspected Doubled Dies. If you've found these all recently (or in the same box) I recommend reading up and looking at more images of doubled dies to help train your eyes for these things. Doubled dies aren't super common, so finding a lot that look doubled to you is a sign that maybe you don't have a clear understanding of Doubled Dies. Check out
http://www.coppercoins.com/ to see if there is a listing before posting. Try to match up your coin and give us a hint of which doubled die you think your coin might be. Although, of course you are always welcome to post when you are not sure.
As most people will tell you from their experience, it's tough as a beginner to tell the difference between what is a doubled die vs what is the much less desirable Machine/mechanical doubling,
Die Deterioration, etc. but eventually with enough quality examples and reading you will become an expert :D
Excellent advice.
