I'm looking for a list of the top collected coin errors, is there anything on line or in an old coin news? I know Canada coin, but I'm not looking for the small errors, just substantial ones. 1946 half dollar hoof through date, this error is easy to find information and has substantial extra value. I tried to find information on a 1943 birds nest cent and didn't have much luck. I'm looking for a list that could show me if my errors are sought after and have added value.
