Gary, Proof has nothing to do with the condition of the coin. Proof is a description of the process by which a coin is minted so a proof coin will always be a proof coin regardless of how much wear or damage occurs. To me, this looks like a proof. Ben's hair, the Liberty bell, and the eaglet are sharply detailed indicating a proof strike but a remote possibility one heck of a full MS strike.
I cannot tell from the photos if any hairlines or light wear is present, but assuming it is since it was found in a cash register, the Heritage Value Index lists PR58 1955 @ $23-31 and PR63 @ $35-45. I would recommend a dip in acetone. It might remove the haze and won't harm the coin. If the haze is removed by acetone and the mirrors are restored, do not rinse with water just another dip in clean acetone. Water, regardless of whether it is distilled or not, will leave water spots on proofs.
