casino coins is close, there is also a colour changing chinese coin trick (regular and jumbo).
wouldn't the basic spellbound change routine qualify or aligator coins perhapse.
mark ladveridge has a routine that uses an okito box and a special coin (common coin gimmick) to make the coins change places, also the same version without the box using a little coin wallet instead called the "walk about coin routine".
hope this helps.
