I was given South Africa long proof set 1967-however 1 rand (0.800 silver) doesn't look nice(some dump or water damage?). Is there any way to clean this coin? Any idea would be appreciated..
I don't... Is always better to ask someone with experience in this matter ,instead to pretend that we know everything...
I don't have to-just was curious if it's possible--I'll not lose or gain anything--maybe some knowledge for the future...
I recommend swallowing it and allow the gentle digestive juices to give it a soft clean. Keep an eye out for it next morning!
I've always respected you @sammysilver for your posts ,but I'm sure you should posted this advise in JODE section not here....
Original finish and naturally toned coins are highly sought after even if not perfect, they bring more premium than a cleaned coin and sometimes much more. Stackers like me couldnt care less about if a coin has been cleaned but to a high end collector it would matter. If it's in original packaging it's best to be left that way from what I've been told.
I would try using a little acetone. The lady who comes from emop and cleans my apartment once a week told me that with the help of acetone you can clean a lot of things. I was very surprised when the coins were cleared of dust and other dirt in a matter of seconds. The main rule is not to rub too hard. Carefully take a cotton pad and wipe each coin.
Life imitating fiction. I’ve always joked about swallowing coins to clean them. Since Covid I have been gargling with colloidal silver solution. It is 20 parts in a million. Probably the same effect as swallowing a fiddy once a day!
I have tried the aluminium foil + salt + sodium Bicarbonate bath trick but it doesn't work on low purity silver such as 50%. It works ok on 92.5 but I have never tried it on 80%. It is no-touch method for removing patina. It won't do much else in the way of cleaning.
