There was a coin at a Spink auction a few weeks ago that only showed one side of a coin. I think that it was an 1826 proof penny, so not a cheap coin. Just seemed a bit strange to me.
Somebody at work got very confused about this the other week about an invoice from a USA company. They thought that 02/10/20 was the February 10th of this year. I had to point out that the year was wrong. I did laugh.
I doubt if the "Honest person" was bidding for the coin. It looks like a four figure price coin from a dealer, if fit was for sale in a shop. Unfortunate.
I did see a VG or thereabouts F8B sell for about £300 on eBay last weekend, but surely there is no way to tell what dies were used on "The slightly worn coin". 😁
How the hell can they grade that MS64? It clearly has wear on it. It is disgraceful, and blatant to anybody who actually looks at it before buying it just on the grade.
