Hammered Sterling and Bronze Disc Layer Necklace

Sterling necklace with two layers of sterling and I think bronze hammered discs or coins. Similar to a piece I saw online for Silpada, but this doesn’t have the Silpada signature tag. So I don’t know if it is or not. The silver chain and coins both test as silver and the clasp is marked 925. I believe the lengths are 16 and 18” but I can’t find the pic with the measurements. Excellent pre-owned condition.
