Hello all! This is my first post on the forum. I've been a coin collector for years, mainly of silver proof sets, Franklins and general silver. The one thing I've never gotten into is looking for errors, vatiations, DD, RPM, etc.
Tonight I went through a load of old pennies I had stashed away, and set aside about 100 for further inspection. What is the easiest way to spot DD and RPMs? I know if sounds like a rookie question, but I'm a rookie at this part of the hobby.
Interestingly enough, I found what I thought was going to be a silver quarter in the bucket of loose change. Couldn't believe that would have slipped through seeing that's what I always look for first when I'm handed change. It turned out to be a 2004-p Wisconsin quarter without the copper ring around the edge. Is that a common variety?
Best and thanks for answers.
