Not sure, but this spoon came from a family that collected anything that was related to Tiffany & co. as the lady that passed away had a Great Grandfather who worked for Tiffany & co as a sales rep and died in 1941. My guess is that Peltier presented this spoon to him and was kept with their Tiffany Collection. As far as they were concerned nothing to do with marbles. Thank You. Richard Tisch
