The Minox C is a subminiature camera that uses 8×11mm film in Minox cassettes, continuing the format Minox established for its pocket-sized cameras. The C Black is the black-finished variant of the Minox C body.

UK auction hammer results for the Minox C Black are thin, with the two recorded sales falling between roughly £110 and £180 — wholesale saleroom levels that exclude buyer's and seller's commission. As of 2026, that gives a midpoint near £140, though with so few data points the price a Minox C Black sells for at auction today depends heavily on cosmetic condition and whether the original case and chain are present.
