1967

The month following closure of its on-site Bullpen casino, the Nevada State Prison sold the brass coins that inmates had used for decades (since 1932) for wagering and as currency. Sets, containing one coin of each denomination — $0.05, $0.10, $0.25, $0.50, $1 and $5 — went for $30 to $50 apiece, depending on their condition.

Proceeds went to the facility’s Inmate Welfare Fund, which subsidized recreational activities.
