.925 stamping update: These were purchased at Dallas Market in the mid 80's. The cross is stamped .925 Mexico and the others are illegible with visible stamping not guaranteed, but are usually stamped Inside the round wire, but it may have oxidized. 

I am the original buyer and owner. Have fun making something cool because I clearly never got around to it.

Condition: Scratches and oxidation are commensurate with age. 

They are very thin and lightweight. What would you make with these? Necklaces? A pair of earrings?
