[QUOTE="GDJMSP, post: 299615, member: 112"]It's pretty simple really - and you certainly don't have to take my word for it, you can ask any professional grader - but wear is caused by a coin being in circulation. Where as what is referred to as rub in today's vernacular, ( it used to be called cabinet friction or cabinet rub ), was something that happened to an MS coin while in someone's collection. Since most collectors used to keep their collections in a coin cabinet, that's where the name came from. And the cabinet friction, or rub, came about as a result of the coin moving slightly while it was held in this cabinet. Now some may argue that is merely a question of semantics, but it really isn't since the two things - wear & rub - have very distinct and different causes. The bottom line is that professional graders, and that includes those in the ANA not just the TPG's, differentiate between the two. A coin with rub can be and is graded as MS while a coin with wear is not. Of course there is a littel more that goes with that - like how do you tell rub from wear ? Well since wear is a result of a coin being in circulation a coin with wear will also have other characteristics that are consistent with a coin being in circulation like marks, dings & hairlines. While a coin with rub will not have these characteristics. Now someone will say that even MS coins can have marks & hairlines.
