eBay is just one marketplace out of many. Some prices might seem "high" and others "too low." If you are interested in pursuing Lincoln cents, you will do yourself a real favor by finding the coin stores and a coin club in your area. Buy "The Red Book" for starters and then acquire other books from there. Go slow on buying coins. Stay away from eBay. If you do not know what the "D" is for on a cent, and if you insist on calling them "pennies", then you are a sheep waiting to get shorn. We all know the words of Aaron Feldman who said, "Buy the book before you buy the coin." Michael ANA R-162953
I sell on eBay and I agree with Michael - unless you know exactly what to look for in an honest eBay dealer, do not buy from there. There are some honest dealers, but unfortunately, they are few and far between.
