The coin term, "Slider" is a term originally coined to describe a condition (slide marks) associated with Mint State coins stored in wooden drawers which should have been graded as MSNC (Mint State Non Circulated). Someone, in their infinite wisdom, decided to begin using the term to describe coins which have some, questionable, circulation issues. This is my opinion, what's yours?
Well, you need some word to describe coins that an unscrupulous seller tries to "slide" into mint state.
I've always heard the term as an AU coin that a dealer (at least originally--now TPCs as well) used to "slide" a coin's description into MS territory.
Personally, I have never understood why anyone ever dreamed up the term "Slider". I have yet to see any hamburger, small enough, that you could gulp down in one bite. With that said........and so that I'm not accused of "clowning around"........you're probably right........or at least close to it. ~ Chris
Cabinet wear is now the term that you are using for slider. A slider in todays terms is no doubt a coin that has enough wear to be an AU. But the brilliant minds at the TPG's have decided that wear is acceptable in the mint state category. Go figure It is not only a MS grade that can be a slider. All coins are now graded by the market toning, and preservation (originality) are now bonus's and can turn a VF into an XF etc.
I agree the term brings to mind a coin that has just high point rub from being slid across a surface. Right or wrong?
My understanding of the term was an analogy to baseball. When the runner looks like he wont make base, he slides full length to try to get there. He will be close to making, it or he will just fail. A coin will bump a grade or not if it is close
We've gone round and round and round and round on this topic many times before: https://www.cointalk.com/threads/thoughts-on-cabinet-friction-from-a-professional-grader.337901/
I thought a "+" was supposed to indicate this if it was close to the next grade. The problem, it seems to me, is that the TPG's need wiggle room for classification. What is circulation wear and where is the line drawn between circ and uncirc? Post mint wear, regardless of cause, should be treated as circulated, IMO.
I always understood that a "slider" was a coin that was just shy of mint-state, that some would try to promote as a fully mint-state coin.
