You are buying presidential partial proof set of 4 proof $1 coins (Fillmore, Lincoln, Buchanan and Pierce) from a 2010 silver proof set purchased from the U S Mint. These are NOT silver but mint proof coins.
You are bidding on or buying coins very similar to the pictures. Grading is subjective so please look at the pictures and judge for yourself. Even though these coins come from the U S Mint, they are uncirculated gem and proof and not always perfect.
Contact me with questions and see my great feedback to bid with confidence.
