Thats insane. I don't know how it was created but for sure a logjam in the minting chamber.

Pretty sure I saw that on Fred Weinberg's table many years ago at the FUN show. He also had one that was 7 or 8 full coins fused together.

I'm thinking that if you kept feeding coins into the striking chamber while not allowing them to eject (such as if the first one got jammed), you could end up with a mishmash like this. Interestingly, I'm not seeing a section for this over on error-ref.com.

It's there - under Bonded Coin Errors. Here's a link:

- Part VI: Striking Errors - Bonded Coins

Spence pretty much described it...Here's my understanding of how this can occur (from a conversation with an error coin dealer several years ago - not Fred Weinberg, not Jon Sullivan).

As I understand it:

- An initial coin is not properly ejected from the die chamber after it is struck (i.e., remains in the chamber, either wholly or partially); if the collar was not properly in place when the dies struck the planchet, the coin may be struck off center or be a broadstrike.

- The planchet feeder mechanism malfunctions and feeds one or more planchets into the chamber.

- The dies then strike the multiple planchets in the chamber and, because of the high pressure involved in each strike, the coins are bonded/fused together.

- the improper feeding and striking of planchets can repeat causing a bound pile-up - what appears to be shown in the OP's image.
