This is true. Would you also agree that the presence of verdigris can accelerate further corrosion, and that removing it can help prevent further...
I think you're confusing "ferrous" with "ferocious".
The "coin #" I see on PCGS CoinFacts is different for proof vs. business strike -- but also for BN, RB and RD.
It strikes me that the "carcinogenic" concerns about cobalt chloride are probably more large-scale -- do we get in trouble with water quality if...
I think he didn't know what "ferrous" meant in the article he read, and substituted "real".
Cobalt chloride isn't used in bulk as a dessicant. It's an indicator -- it changes color from blue when it's dry to pink when it's not. Add a tiny...
Cobalt chloride is poisonous if you ingest it, but it doesn't produce any gases. As long as you don't put it directly in contact with your coins,...
I feel like I should be ratting you out, but I can't decide if it's Religion or Politics. And the rules don't say anything about Common Sense. ;)

Remember to use a glass you don't care about. Strong bases like lye will etch glass as well, eventually.
After lots of discussion here, my understanding is that it's the work hardening done on copper-nickel that makes the date more resistant to...
Any other coin will display a date and mintmark. There's no effective way to restore dates on anything other than nickels. Etching a coin that...
Well, first of all, the VerdiCare formula is proprietary, highly effective, and apparently a good seller, so I can't imagine @BadThad would be...
Hi -- welcome to CoinTalk! That's one of the colors that copper can turn when it's exposed to the elements. It's just surface corrosion. There...
1918/7-S acid-restored coins consistently go for hundreds of dollars. Any of the key dates can go for $10 or more. You may think the people...
Ferric chloride really wants to turn into rust and hydrochloric acid, so it acts a lot like the acid. I'm not sure why it became the standard for...
You just won't find quarter-eagles near spot price, at least not at current gold prices. Even cleaned or damaged, they still carry a numismatic...
