militaria

noun

1. (plural, plural-only)Military or police artifacts.

   “According to Denby, who has a store at 20 Birch Ave., the militaria market has grown up in recent years. "It used to be that only school boys were interested in collecting these things." Now with cap badges going for up to $4,000, the market has matured to the point where the collector has to know what he's doing or he can get "stung."”
