NCR dollars, or Money in Fallout 2, are the standard currency of the New California Republic. The NCR introduced its own money around the turn of the 22nd century and initially it relied on coins minted from gold. By 2241, the economy of NCR dominated the West Coast and coins became universal currency, used by the three big powers: NCR, Vault City and New Reno. During this time bottle caps had become worthless in these regions.
