I recently helped an older woman with her unwanted gold. Went
through a pile of stuff examining, testing, and sorting. It included
a fair amount of dental gold, complete with rotted teeth. There was
an enormous gold bridge that had been her grandfather’s! Since she is
at least 80, you do the math. So we popped out teeth, cleaned
everything up, and shipped it off to G&S Gold who have no assay fees
over 50dwt and pay 95%. That bridge must have been very high karat,
because her check was about 60% more than my estimate.
I don’t know what the standard gold alloy is for dental work today,
but back then it must have been 22K.
