Found all this jewelry , last week on the street's of Nola! Not sure if earring's are real gold&silver. Mardi Gra's necklace is silver, maybe small chain, chain earring. Thought antique looking brass ring was gold at first, found in crack in street. Finally, friday found a greek (?) copper or bronze coin, in street curb, smaller than dime, pitted , look's genuine. Some idiot put super glue on the back. Soaking in acetone, then hot peroxide , then pick with wooden tooth pick, then olive oil. Did better on the street's in a week, than beach in several month's of hunting!
