p/s: Tips to brighten rusty old and dark coins. Just soak them in vinegar (not fruit vinegar). Within a few minutes, the money will be bright insyaAllah, without the need to be scrubbed. If scrubbed with a toothbrush will be faster.

Do not rub the coin with iron brush or scrubbed at rough places arbitrary, because the money will scratched and will probably depreciate.

Then for silver coins, just scrub using a toothbrush with a toothpaste on it. Save money. Wallahu a'lam. :-)
