Homestake Goldmine gold bar keyring -- Never Used --

This gold bar keyring is from the Homestake Goldmine, Lead SD. It was once the oldest Goldmine in the United States. But slosed down in 2002. This was probably a safety award, given for # of days accident free. It is numbered and comes in a black satiny bag. The bar itself measures approximately 1 1/2" × 3/4" × 3/8" I do believe it to be plated, not solid gold. *** Never Used ***
