The Smith Invincible is an early-era camera that surfaces only occasionally in the UK collector market. With limited published reference material, it is treated primarily as a collector item rather than a working photographic tool.

Auction evidence for the Smith Invincible is thin: a single UK saleroom hammer result of £180 from 2017 is the only verified data point on file, so today's value should be read as indicative rather than a settled market price. Because this is a wholesale auction-hammer figure, retail or dealer asking prices for a comparable example would typically sit higher, and what a Smith Invincible sells for at any given sale will hinge heavily on condition and completeness.
