1985-S Memorial Cent Proof ?

Yes I agree with @sw--it is a proof that has circulated a little bit. The portrait, Lincoln Memorial, and letters are all frosted.

Years ago, (Yes, Coop. I know I'm old! ) I worked in a game room. We had pinball, video games, pool tables and the other coin-op machined found in 1980's arcades. I would find the plastic cases from Proof Sets in the trash. When I saw them I would recover the coins from the games.

A kid about 15 years old came up and asked for quarters for a proof SBA, so I asked where he got it. He said he had a bunch of coins like that he'd received as gifts from his grandfather. I said he really should hang on to them, but he didn't want them. He kept breaking set and using them in the games and for a hot dog now and then.

One day I told the kid that I would buy them for $3 each, so he started bringing them straight to me. I must have bought 25 or 30 proof and uncirculated sets going back to the early 1960's. He would bring in 2 or 3 at a time. He was happy with getting extra quarters to use in the games and I had a bunch of proof sets that didn't cost much.

I always wondered if he ever got into trouble for selling off his grandfather's birthday and Christmas gifts. I still have the silver sets he brought in.

Nice find in the wild, congrats.
