There were a number of incredible errors coming out of San Francisco in the early 70’s including the 1970-S quarters struck on Barber Quarters and a 1940 Canadian quarter. These were sold in an auction (Govt. seized property auction??) after getting an OK from the Secret Service. The overwhelming consensus is that these errors “had help”. The coin in the OP is also from San Fran in the early 70s and it wouldn’t surprise me if it was also part of that auction. Anytime I see a spectacular S Mint error from the early 70’s, I’m always suspicious that it had help.
The set of Proof Ike Off Metals are not from the Calif. Safe Deposit Box deal (I bought that deal intact)
I once handled one of these folderol Proof Ikes struck on a cent planchet, where the piece had two flat sides at approximately a 120 degree angle. The rounded point of the angle was towards the center of the design. Obviously three planchets were in the press during the strike, at (IIRC) 12 o'clock, 4 o'clock and 8 o'clock. (Might possibly have been 2, 6 and 10 o'clock, but obviously deliberately placed.) The strike(s) squeezed the cent planchets against each other, creating the flat sides to the angle. TD
I like it but very very questionable as to strike, error, or FAKE can't make sense of it. I would surely like to hear more from our qualified CT experts...
If it was just an Ike dollar all the way through, it looks like a bow tie clip. Seems unlikely for a cent and dime planchet to accidentally fall into the dollar hub and be struck together. And even if it was an accident and a mint error, it should have been pulled and destroyed. Creating errors (even ones that are graded and sell for huge amounts of money) taints the hobby, and the subset hobby of error collecting. It doesn't matter to me if this sells for a huge amount, the integrity is in question. It is unlikely that this coin could have circulated (unless found in a mint bag) and reverse engineering of the paper trail would probably expose this as not a true error.
I met him at the Baltimore Whitman coin show the last time we were able to go. He gave my son a pretty cool off-center cent.
Won't tell you anything. They ARE real, and were struck in the mint, but it was the fabrication of some mint employee, not something that "just happened". Smuggled. Especially in a proof coining press striking dollars.
No. "Mint-assisted" already implies someone at the Mint helped it along. "Mint-employee-assisted" is redundant as the coin could not have simply made itself.
