How much value is decreased if jersey is washed?

[icollectDCsports]

Grass and dirt stains -- and other marks from game play -- can increase the desirability and value of an NFL jersey. I have known collectors of NFL jerseys who have made purchase decisions based on such stains. A number of variables in play here. A jersey that can be traced to play in a particular game -- and which may also facilitate photo matching -- may well be more desirable than a clean jersey, maybe not to all but to some, and the additional demand may equate to greater market value.

Collectors' preferences may well vary depending on the sport, but there is one area of collecting where the market's preference is quite clear -- game worn hockey jerseys. Removing stains (blood, stick marks, etc.) definitely removes value there. The more wear the better, and those that can be described as "hammered" or "destroyed" (rare in the current age of many sets of jerseys and better cleaning methods) with such stains, damage, and repairs selling for a premium.
