Vintage Caesars Palace Goldtone Coin Medallion Pendant Necklace 25th Anniversary

This vintage Caesars Palace coin medailion necklace from Las Vegas features a gold toned profile of Julius Caesar and the text is "CAESARS PALACE LAS VEGAS - MCMXCI (Roman numerals for 1991). It commemorates 25 years of business. The Palace opened in 1966. The medallion is typically made of gold-plated brass or a similar metal alloy. I just know it is very shinny and gold color. The chain length is 24".
