Community Currency
  
Community currency is a local legal tender that can only be used to buy local goods from local businesses, i.e. their local community.
The reach of the community currency can be geographical or association-based. A poker chip in a casino is community currency; a Disney Dollar used in DisneyLand (or World) is a community currency. In a historical sense, the Confederate currency was a community currency.
Community currency can be viewed as a way to encourage buying locally, because you can’t spend it anywhere else. Waste or non-spend of these kinds of currencies is a huge profit margin business for those who sell the currencies. Like…if you get that $100 chip in Vegas and never cash it in, the casino just made about $99.90 off that chip.
