EUC vintage welded copper bangle bracelet

EUC vintage welded copper bangle bracelet There’s a few scratches, dents, patchy spots from the years. No hallmarks. But it’s still a solid, tough, shiny piece! Has that nice deep rich copper colour! More brown-orange tones than the pinky tones that is closer to rose gold. This is NEW, unworn, unused but it’s been in storage, knocked around in a huge baggie during moves for over 50 years. New vintage c. 1970s. No hallmark but I believe it’s copper. 2 6/8” or 66 mm diameter, 2 mm thick x 5 mm wide Group photos show the variety in the collection
