Hubby picked them up at a yard sale today but we have no clue what they are. Magnet doesn't stick to them. Gold doesn't tarnish, so maybe brass? Or a bunch of different precious metals mixed together? Anyone familiar with smelting? The bag was buried in a box of very old railroad train stuff....metal thingies that went on the side of engines, two horns, etc. He didn't even see the bag until he got home with his haul. So I said I would ask here if anyone knows what this could be?
