hi chris ---i remember less that ten years ago being in the white house hotel, when the battery was running in one of your neighboring towns to the north, and a bloke was trying to peddle gold buttons to the people on my tour. he was the battery operator. i don't know if any one puchased any of those nice round multi oz. nuggets or not. but i guess that that really never happened. those gold buttons don,t look too good on a chain anyway---hoss
