About 800 of these MAD hotstamps on Craigslist. The story is they came from an old guy who ordered them in the 1960s. They don't look like china clays... What's your take? If I scoop them, I'll probably resell here.
Pro: Spots are decent, they could at least plausibly be ASMs, Paulsons or TRKs
Con: Breakdown and denoms look poor. Best guess is 100 $1, 150 $5, 150 $25, 150 $50, 250 $100.
Worth a detour on the way home from work to check them out?
