[QUOTE="the duck, post: 70886, member: 138"] Silver coins wrap loosely in aluminium foil and drop into boiling water for 10 minutes then rub with bi carb Or silver coins in CLR for half an hour and then rub with bi carb Copper coins in olive oil but this takes a long time and electrolysis may be better Warning if it is a key date coin take it to a professional as cleaning them can devalue a coin up to 90 per cent depending on how you clean it [/QUOTE]
