Good Morning Dave,

The non-Nevada silverstrike guide of Dennis Finn and Christie Gregeory. List them as--Generic strikes-- and Deadwood, SD. No specific Casino name. There seams to be 6 in this series. They are at the top of a long list of strikes from here. There is no mimt mark and .999 is on the rim. They are retired from play. Nothing else. Hope this helps.

I might suggest, that that you. Or asker refur to this book. Or get in touch with Dennis Or Christie. Probally more information somewhere else. But this is all I have.

Dan
