Working on a set of $20 large cents and doing fairly well so far I think (ok this one cost me 25 once you add in shipping but in this case I not counting that as cost ) Looks like a bit of the EVIL verdigris but verdi-care should fix that ok . This one is from the same dealer that sold me my nice new 1962-d MS64FBL franklin for only 55. I think I'm getting to like this dealer PS Sellers pics
Great idea for a set, looking forward to more $20 pieces. And somehow I think you are going to cherry pick some nice keys and varieties for that price point.
