Almost perfectly rotated at 90 degrees each strike. Someone please convince me this wasn't done on purpose. Amazing nonetheless! I bid $744 and was outbid. Still,has 5 days left to go. Probably will get over $1,000.
Lovely! Don't ever bid days before it ends.. You are just making it more pricer.. I wait until the last seconds! That's how I win errors such as this! This coin was from Sullivan Numismatics
It was done in the mint, but I would say it was almost certainly "helped" by a mint employee. The finished coin is a snug fit inside the collar, and typically won't just drop back into place in the collar especially it will just drop back into place four times with a nice neat 90° rotation between each time.
It's impossible to say whether this had help. I have seen several in-collar triple strikes, so it's not hard to conceive of an in-collar quadruple strike.
Mike, I guarantee you it's genuine. It came in a nice batch of San Francisco sourced errors, including Proofs. (all dated 1965 to 1973) This particular coin was struck at the San Francisco Mint.
Yet another reason to think it was "helped", a lot of helped errors came out of San Francisco around then. Not saying that it's not genuine, as in it was made outside the U. S. mint, but the chances of a quadruple in collar striking, with each strike 90° rotated from the previous one begs credulity. Sure it's theoretically possible to have a quad in in collar strike, with rotation, but I would expect the rotations to be random amounts, or relatively small rotations. Not four 90° rotations.
