Hi, I would like to clean some of my standard $1.00 and 50cent coins as I want to keep the various designs. I have tried cloudy ammonia and seperately bicarb and aluminium foil but seem to have made them tarnish more! I have read the cleaning round 50 cent piece articles on here but need some advice on cleaning them to a shiny condition. Should I use TarnOff or something else? I have a few old pennies as well, what is a good thing to clean these with? Thanks, Blake.
If the mood takes me for some bizarre anti numismatic reason I use toothpaste & an eraser & lot's of elbow grease. Work's well. A numi will pick up that you cleaned the coin in about one nanosecond. Therefore, I wouldn't go cleaning anything of potential value.
Hi, Thanks for the replies, they are just coins I get in change so at the moment only worth face value, just keeping them for the different designs. I will try Hydrochloric acid and see what happens, at worst I can get rid of them at the shops! I only butchered one 50 cent piece and about 10 $1 coins to see if it worked. Blake.
AUTOSOL is a great metal cleaner /polisher u can get it at most auto stores cleans all metals with a little elbow grease i use it on my motorbikes i wouldnt use it on a nice coin but it will bring a shine back to most metals
