I'm no expert, but when an
ebay vendor has a lot of coins that have almost exactly the same "look," I figure they are most likely doing something to them. When I first resumed my quest for nice circulated Lincolns, I bought a couple of coins from the teens that I thought were beautiful. The most distinctive characteristic were that they were veeeeeery clean. After I realized that almost all of his offerings looked the same, I decided to go elsewhere.
