The Nikon Coolpix 4100 is a compact digital camera in Nikon's consumer Coolpix line, using a 1/2.5"-class CCD sensor and a fixed zoom lens. It was a budget point-and-shoot positioned for everyday snapshot users when introduced in the mid-2000s.

Auction data for the Coolpix 4100 is extremely thin: the only verified UK saleroom result on file is a single hammer price of £298 from February 2004, which reflects a near-new example sold close to its original retail period rather than today's market. As of 2026, secondhand demand for early consumer Coolpix compacts is modest, so a working Coolpix 4100 typically sells for far less than that early figure at auction-hammer level, and the 2004 datapoint should be read as a historical reference rather than a guide to what the camera is worth now.
