Manufactured by Dieges & Clust in the 1930s or 1940s, this 10k gold pin back, representing 30 years of service to the Coca Cola Company, is decorated in green and white enamel with 6 diamond chips and an embossed Coca Cola bottle in the center. It measures about a half inch in diameter and is in near mint condition. This and other Coca Cola pieces are from the Thom Thompson Estate. Mr. Thompson collected for over 50 years and was a Coke Bottler himself. He received a “Special Thanks” in Allan Petretti’s Coca Cola Price Guide as follows: “Thom has always been my number one supporter. Ever since the first edition, he has unselfishly offered his knowledge and collection to help make this book better. Thom and Frances are among the countries top collectors. This book wouldn’t be what it is today without their help.” This is a once in a lifetime opportunity to add a piece with such history to your collection. 16680-71QRP
