Keystone A-9 Criterion
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. It belongs to the consumer film-camera category rather than the professional cine sector.
Sales data for the A-9 Criterion is extremely thin: the only recorded UK auction hammer result on file is £100 from 2011, which is a wholesale saleroom figure rather than a retail price. 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.

Frequently asked questions
What is a Keystone A-9 Criterion worth today?
Evidence is limited to a single UK auction hammer price of £100 from 2011, so a precise current value cannot be stated with confidence; condition and working order are the main drivers of price.
How much does a Keystone A-9 Criterion sell for at auction?
The one recorded saleroom result on file sold for £100 hammer, excluding buyer's premium, which suggests this model trades in the modest budget tier typical of mid-century amateur cine cameras.
Is the Keystone A-9 Criterion a collectible camera?
It is a low-volume collectible rather than a sought-after model, and its value tends to track general interest in vintage home-movie equipment rather than any specific feature premium.
