Vintage Brooches /Dragonfly and Cinderella's Coach/ Signed/ Circa 20th Century

I picked both brooch pins up today. The dragonfly came from Salvation Army and the Cinderella coach came from GW's . They both have marks. The dragonfly has "FAS" stamped on it. That could mean "fused alloy silver" or a company known as" Fantastic Antique Silver" which is no longer in business. It looks like it's made with a blue grey stone like enamel and smokey rhinestones. I do think this piece is a silver alloy myself. The Cinderella coach is marked "AJC" which is the "American Jewelry Company Chain". It's a really shiny gold tone metal with a rhinestone roof and lots of detail. Both are about 2" long with swivel lock pins, so they're not real old, but still very nice. -Mike-
