What it is
{"overview":"The Keystone A-9 Criterion is a vintage amateur cine camera from the Keystone Manufacturing Company, a US maker active in the small-gauge home-movie market through the mid-20th century. With just a single data point, today's market value is difficult to pin down, and what a Keystone A-9 Criterion sells for in 2026 will depend heavily on condition, completeness and whether the mechanism still runs.","buying_guide":"As with most vintage clockwork cine cameras, the main points to inspect are the spring motor (listen for a steady run at the marked frame rate), the lens for haze or fungus, and the film gate for cleanliness.
