The Minox Riga is the original subminiature camera produced by Minox, designed by Walter Zapp and introduced in the late 1930s in Riga, Latvia. The "12 Teeth" designation refers to an early variant identified by collectors through the tooth count on an internal mechanism, distinguishing it from later production runs.

At UK auction, hammer prices for the Minox Riga (12 Teeth) have ranged from roughly £920 to £2,200, with the limited record giving a midpoint near £1,560. As of 2026 the price a Riga 12 Teeth sells for at saleroom level is highly condition-sensitive, and the small sample size means individual results can swing well outside that band depending on completeness and cosmetic state.
