Was feeling moth-to-flame-ish today so ducked into busy gold store. Nothing I really liked, so I asked if they had any Mexican silver hidden away, like, actual old coins.
Jackpot! Big tray full of heavy 27g Cuautómecs, 24g Hidalgo grandes + various commemoratives, 20g wreath Hidalgos, 13g Hidalgo chicos, good spread of variants.
I had less than 100 bucks to play with, so I homed in on the cool Post-1905-Reform Cap-and-Ray Pesos, at 12g ASW a little chunkier than US Half Dollars. What really matters is that these were the coins that Humphrey Bogart was begging off of John Houston when he was down and out in Tampico in Treasure of the Sierra Madre (go watch it.) Woulda equalled US 50 cents back then, so, what, maybe 10 bucks now?
They were a tad grubby so I went home and did the non-abrasive baking soda, hot water, and aluminum foil trick on them. After dirt drifted off of them and tarnish transferred to the foil, washed them gently and dried them on a towel. Then I jacked with the settings on the final photo in case I ever want to go for $5 extra profit on eBay, which I don't.
84 grams actual silver weight for 84 bucks. About 50 cents/oz over melt.
