Trimmed cards usually have very little value but in some cases such as the 1952 Topps Mickey Mantle, even trimmed cards can go for thousands of dollars. The most famous 'trimmed' card to date is the T206 Honus Wagner purchased by Wayne Gretzky. The card was actually too large and was trimmed down to it's proper size.

Wax - a universal collecting term for factory-sealed packs or boxes. The term "wax" most often refers to sealed material that was originally released in the early 1990’s or back -- a time when packs were wrapped and sealed in wax paper wrappers. It can casually reference modern era packs or boxes that no longer use actual wax paper.
