Circa 1980's.  Sixteen coins are removed from a velvet bag and counted showing all to be brass.  The coins all change to silver and laid out singly and suddenly all the coins change back to brass.  Touching something of color say red and tapping the top of the stack a coin is removed and the next one is seen to be red!  This happens again with white and a white coin appears followed by a blue coin and a black.  All four colors are touched and then a multi color coin makes its appearance.  Keep in mind there are no shells or palming required and no difficult moves and only 16 coins are used.  Includes black velvet drawstring bag and 4 pages of illustrated instructions.  Condition paint absence and tarnish over all but still a set to work with, condition fair.
