Value is relative, as everybody feels differently about such things. Some people prefer their gamers signed by the player, some people prefer them unaltered from when they were used on the ice. It really comes down to a person by person basis. The more descriptive you are about a jersey when you sell it, the better chance you have of finding somebody who is interested as you'll hit more search terms. One person might value it more because it's been worn, and someone else might consider it the same value as a regular authentic because it didn't see game time.
