It depends on what you mean by "dime sized". If it's a miniature version of a quarter with a complete image on both side, it's not a real coin; it's a novelty item with no special value. If it has part of the normal-sized image of a quarter on it, you may have what's called a "wrong planchet" error. It happened when a dime blank (planchet) accidentally got mixed in with the blanks intended for quarters and was struck with a quarter's image. If you think you have a wrong planchet error you should have it inspected in person by a dealer who is familiar with error coins.
