Hi Guys! Can anyone tell me how to clean gold coins? I acquired a couple of 1986 1oz fine gold coins. One is in a bezel, and thats the one that looks pretty dirty. How can it be cleaned safely? Thanks for your help. Nana
OK, thanks for your response, but I need some more answers. This coin has smudges all over it. Can someone offer a little more than that?
Try a jewlry buffing cloth. Also there is a liquid product called jewl lustre that you dip it into. THey sell it at walmart.
The coin is just the gold amount, so the normal "cleaning laws" don't really apply. I use a flexible shaft tool for these.
Well why don't you just go ahead and dip it in aqua regia? That combination of two powerful acids should take off any and all crud.
I have to respectfully say that I don't agree with this. If you take even bullion gold to a dealer that is unattractive, the dealer will likely offer you a slightly discounted amount for it. Anyone who goes to buy a gold coin, even a bullion piece, will pick out a higher quality example if given a choice. Therefore, an unattractive piece is slightly more difficult to sell than an attractive piece. That said, I would try dipping the coin in acetone to see if some of the smudges come off.
With all due respect, it's a piece of jewlery. I'm sure the jewler buffed it up when he put it in there, and it has almost no numisitc value. So its clean it, possibly knock off $10 but have an nice piece of jewlry, or don't and wear a dirty coin. or if the acetone does work, that's great
Try TCE (trichloroethene) if the crud is organic, which is very likely. TCE must be handled very carefully. Else, ordinary 99% iso-propyl (rubbing) alcohol from your local drugstore with a soft Q-Tip could do the trick. An ultrasonic cleaner (available at BedBathBeyond) can loosen a lot of grit. However the coin should be supported with soft material to prevent scratching against the sides or bottom of the tub. Aqua regia may dissolve the gold, so you'll lose Au if it is in the bath for long. This is also pretty nasty stuff.
You were given the correct answer [don't clean it]. Asking for more answers is searching among mistakes to figure out which one you want to make.
TCE is more strictly regulated than it used to be, and is very hard to obtain. I would strongly advise against using this compound unless you are very confident in your ability handle chemicals.
I am a collector of gold coins from other countries. And there is a gold coin that I like so much. It's so beautiful with a statue of liberty in it. It's a 1923 $20 gold coin. Do anyone of you have that kind of coin? edited - BST offers are not permitted ________________ cutie_tech123 Everyone knows the value of the US Dollar is going down - the only thing that keeps its value is metals - In the early 1900's and ounce of Gold bought a real nice suit - Gold then was around $20 an ounce. Today that same Ounce of Gold Will buy a real nice suit but that $20 would maybe get you a nice tie. To fight off inflation everyone should be purchasing Gold and Silver in some form - Gold Coins - Silver Coins or bullion / bars edited - you are not permitted to post links to sales/commercial sites
You may as well just dip it in Battery acid. Your going to make the coin worse anyway, snicker snicker... If you dont know how to clean it, THEN I SAY DONT!
