Nice original patina, great condition, 20mm to 22mm in diameter, all with original patina and in excellent condition, some are uncleaned. Before the introduction of struck coinage in Celtic lands, Celtic ring money (gold, silver and bronze rings), celtic arrowhead and bell money, were used as currency in Celtic lands in Danube area, France, England and Ireland. Sometimes these rings took a pretty elaborate shape (such as"wheel money" in Gaul, star-shaped rings, interlinked rings etc.) and are very interesting collectible items, that can also be used as wonderful pendants or finger rings.
