I would like $1, $5 and $10 coins!
The History Channel runs a series on "Breaking Vegas".
A retired jeweler was able to counterfeit $10 slot machine tokens. He'd play for a while, then go cash in the
phoney tokens.
The investigation started when a NJ casino reported an overage of $10K in inventory. Other casinos found similar overages.
One casino hasn't been able to cull all those tokens from their inventory.
