If any of you like your gold scraps and have some $ you don't know what to do with, here is an idea: https://gsaauctions.gov/gsaauctions/aucitsrh/?sl=31QSCI20088003
Let me guess all this stuff fell off the conveyor belt at the local post office and got somehow misplaced in the management's office till someone happened upon the lot. I guess that's a deal?$$ I'd have to physically look at the stuff and not bid on pictures. Hope the winner makes a good return on investment.
That looks like lab surplus to me. Outside my wheelhouse, but I'm guessing there are people willing to spend an hour or two calculating the minimum gold weight in the lot, then bidding on that basis. It's unlikely you'll get less than you paid for, and quite possible you'll get a bonus.
