Multiple bonded strike mint errors occur when a “traffic” jam of coins happen in the coining chamber and the coins continue to be struck repeatedly by the hammer die so they bond together as one piece.
Bonded multiple strike pieces are worth thousands of dollars and the more coins involved and the more “messed” up it looks the more valuable. The bonded nickel strike imaged above sold at Heritage Auctions for $4,887.50 and add to that a 10% buyer’s premium.
