1879 rare shield nickel only 1,100 minted ever

1879 shield nickel. So rare to find one in this condition with collectors snagging them up and keeping most of them, I have 1 in perfect cameo mint proof condition 1 out of only 1,100 coins like my coin minted. I bought it at auction so I paid a good chunk of change for it. I will keep this up for a week for sale. If it doesn't sell for a good price, I will return the coin to my own collection for another year. Hugs.
