Antique Coin Charm Bracelet

A great antique bracelet with coins for charms: based on the clasp and bar links I would estimate this dates to about 1900-1920. I have no idea about the coins: thought to be replica brass coins, but I am completely out of my depth about coins like this! The bracelet is 6.5” long and looks to be a gold filled watch chain style link. There are 4 different types of coins (3 duplicates and one single) I have left all antique patina intact. The antique spring ring is a bit stiff but still functions. A really unique antique charm bracelet!
