Something tells me that someone has gotten the Chinese counterfeiters to pair up some obv dies and strike double headed copper 1943 cents. (Looks like the paired a D and an S die.)
He says the auction is for 1 coin only, but has 30-40- on hand and any xtra coins purchase is 15 cents additional shipping cost...
The seller has most of the other denomination coins. I bet he did get them custom 'copy'ed for him by a Chi coin sweatshop. He's been selling them for a while.
