A price guide for Case pocket knives is available at AllAboutPocketKnives.com. The guide bases its pricing on the average sales prices of near-mint-condition Case knives sold on eBay.com from around 2011.
The pricing guide provides an approximate value of specific Case knife models including the Congress, Trapper, Moose, Whittler and many others. The guide breaks pricing down further for each knife by year, pattern number and handle type, as of May 2015.
The creators of the Case pocket-knife pricing guide only used products from eBay.com sellers with at least 75 items sold and 99.5 percent positive feedback. The guide omits Ebay.com listings with no pictures or low-quality pictures.
