Archie and friends,

Green Duck Corporation mutated into GDC. Unfortunately for them, they went completely out of business last summer. I believe on June 1, they sold off all their assets. That's why there are/were a number of replacement G or S mint strikes. some of which were very short runs before the Millenium strikes made their appearances. Barbary Coast is the prime example with a run of only 50 of the S mint made each of their four tokens. Gold Coast had a run of 125 of each of their four tokens. Some of GDC's dies have been reused with an obvious new plug to change the mintmark.
