Fred Weinberg recently discovered, in an old and dusty file, one of Mike Byers' price lists on major mint errors from 3 decades ago! It is a blast for error collectors to look at. There are many major errors listed that sold for a fraction of what they bring today. One example is a 1900 Indian Head Cent struck in gold that Mike purchased from the Beck Collection in 1974 for $7,750. Today, this mint error would easily bring $75,000.
For many, collecting mint error coins started out as just a small hobby. It is amazing to see how far this segment of numismatics has grown in the last 3 decades. It is one of the hottest areas in numismatics with thousands of collectors focusing
on mint errors.
