All the riverboat chips are recarved by a jeweler in NYC during the 1930s. Years ago I bought a bracelet of 4 chips with his business card. Kenny Craig agreed with me but me, Kenny and the other ivory collectosrs still wanted them, none the less

All the genuine “riverboat” were carved by the same guy. His letters are quite distinctive

The jeweler put all the chips in bezels and were sold as bracelets
