Various shops in Mafia are of type NPCCOIN, but only the non-meat-costing items can be bought while treating them as coinmasters (e.g., in the coinmaster frame or ASH).
The exception is Cosmic Ray's Bazaar, where the meat-costing item is purchasable, as it's registered to the coinmaster and not an NPC store.
