The Zeiss Ikon Polyskop is a 6x13 stereo camera, taking paired exposures on plates for stereoscopic viewing. It dates from the early 20th century era when 6x13 stereo plate cameras were a standard format for amateur and serious stereoscopy.

Sales evidence for the Polyskop in 6x13 format is extremely thin: the only recorded UK auction hammer result on file is £97 from a Christie's sale, which sets a wholesale saleroom benchmark rather than a retail price. With just one data point, it is not possible to give a meaningful range or median for what the Polyskop is worth today in 2026, and condition, completeness of the lens pair and shutter function will drive any individual result.
