With any sport, hand autographed, authenticated merchandise is a treasured collectible. These items should be considered investments and kept within the bonds of family as long as possible while they increase in value. Anything with a verified signature has value.
Medallions are also a great collector item, though some are naturally more valuable than others. They increase in value depending on the driver and age.
Lithographs, shadow boxes and paintings retain or gain value depending on the driver, the artist of a lithograph, painting or print, and any peculiarities of the piece. This type of memorabilia can be very valuable on history, age and size..
Replicas of favorite or popular drivers' cars are always a big draw for collectors. NASCAR diecast cars typically come in two scale sizes, 1:24 and 1:64. Diecast haulers, motorcycles and other vehicles are popular, too.
Mugs, steins, plates, programs, race tickets and coins are collected by fans and can be very collectable if pre 1970 in age. While shirts, hats, jackets are always in fashion on the NASCAR circuit, they aren't considered valuable when they do not have a authentic signature present.
