I had a guy once come into pawn shop where I worked claiming he had an uncirculated Roman silver coin. He also claimed he had a 1000 carat opal. He was about 6’5”, 300 lbs and unwashed for maybe a week. Seemed a bit nervous.
I was glad I had my Glock 30
Uncirculated, riiiiiight. :^D
1000 carat opal, hmm, not unheard of I guess, that’s almost enough opal to make a bowling ball, which obviously would make any bowler the envy of the tournament, unless Walter brandished a firearm.
