Riken Optical Gokoku No.1

The Gokoku No.1 is an early Japanese folding camera produced by Riken Optical. It is a pre-war small-format folder, representative of the type of consumer cameras Riken made before its later Ricoh-branded output.

Auction data for the Gokoku No.1 is extremely thin: a single UK saleroom hammer result in 2023 stands at £1,400, which is the only reference point for what one currently sells for. With just one wholesale auction sale on record, that figure should be treated as indicative rather than a settled market value in 2026, and the true worth today depends heavily on condition, completeness and bidder interest on the day.

Frequently asked questions

What is a Riken Gokoku No.1 worth today?

The only recorded UK auction hammer price is £1,400 from 2023, so on the available data a Gokoku No.1 is worth around that figure, with significant uncertainty either side.

How much does a Gokoku No.1 sell for at auction?

With just one verified sale, the Gokoku No.1 has sold for £1,400 at UK auction; further results would be needed before quoting a reliable price range.

Why is the value and price information so limited?

The Gokoku No.1 appears very rarely in UK salerooms, and our sales history contains only one hammer result, which limits how confidently any market value can be stated.
