John Genualdi provides this information about its authenticity. "I bought the chip from Albert Rollins, Sr. and he said it was from the Casino Camuy in P.R. It is pictured in the "Catalog Numismatico De Puerto Rico" by Efrain Archilla-Diaz on page 215 item #092." Gene Trimble mentioned that the same "CC" logo was used on chips ordered in 1938 for the Chesterfield Club out of Kansas City. I wonder what the connection is?
