I brought these beautiful oversized coins back from my last trip to Israel. They have an imprinted view of the old city of Jerusalem on the front. The back is perfect for engraving. I'm not sure what the metal is, but it doesn't seem to tarnish. Just under 2 inches across.
I made this one into a pendant, embellished with a silver bead and hung on a black velvet neck cord. The 18" neck cord has finished ends and a silver lobster clasp.
