Card "pips" theme brooch and bracelet

Here are a couple of pieces I picked up at flea market or thrift sales. I love playing traditional card games like Gin Rummy or Cribbage, and I have always enjoyed the graphic qualities of playing cards, so these caught my eye. The bar pin has the clubs, diamonds, hearts and spades in enamel on each end. The bracelet is a type of charm bracelet I think. I'm guessing the pin is from the middle of the last century and the bracelet is more modern, but I don't know for sure.
