Antique Feathered Design Bangle

This silver has turned gold and copper in some places in the inside. Its a very old large bangle from the late 1960s when they became very popular. Its not stamped but it used to be, it doesn't stick to a magnet and it passes sterling silver test. It is worth alot to me, and I have seen a few similar but not just like this one, on here. Its not costume jewelry it's just pretty old.unisex for sure looks and fits a man well. Goes good alone or with a lot of bangles like I wear. Not really sure if I wanna sell it as I know the history and how old it is. And it came out at a pretty cool time. My aunt bought it at Woodstock or traded for it or something I never asked too many details. The fact it came from 1969 Woodstock Festival and she gave it to me at a young age. I have surely worn it a lot because it's got such a cool story behind it. My price on this item does not have to be agreed on. I think its cool and I dont mind if it sells or not. Thanks!
