WWII Era Coin Bracelet, Mexican 20 Centavos Silver Coins, Japanese Aluminum Coins, 1930's - 1940's retailer

This vintage bracelet has 20 overlapping 20 Centavos Mexican coins. It is difficult to see the dates because of the overlap but they appear to date from the 1930's - 1940's and have a silver standard of .72. The coins are soldered to a chain on both sides and the total length is 8 inches, less in wearable length because the hook clasp is attached to the center of the retailer two end coins. The width is approximately 1 inch excluding the four dangling coins that extend the width to 1 3/4 inches. These coins are aluminum Japanese coins from the early 1940's. The bracelet has a weight of 76.2 grams. It is in very good condition but soiled and we have not tried to clean or polish it.
