An 1818 mint set.
After acquiring an 1818 CB quarter the other day, and with the 1818 half I already had, I thought about an 1818 mint set. I didn't realize there were only 4 denominations minted in 1818. Three of them are relatively easy coins to find, the fourth might pose a problem. Prices for that coin with a limited number of known pieces are not astronomical, but finding one for sale might be a problem.
