Using mint in a description is common place and been around for some time.
long enough to take it as a guide that the item is in pretty good condition - but not actually mint. This description floats from between a conscious exaggeration to an our right lie and should treated accordingly. At best it derives from the sellers enthusiasm to sell.
But there is no substitute for viewing the pix provided and asking for more if what is already provided are inadequate.
But, I do notice on ebay that some sellers take pix of the models that are listing with all lights of and just waiting for the camera's flash to provide lighting so my naturally suspicious mind says, give that one a wide berth and so I do exactly that. Caveat emptor = let the buyer beware
