Good morning coin talk I have a copper penny with some white corrosion on it and would like to get a closer look at it. What would be the best way to remove said corrosion without damaging the coin ?
BTW!!! Not the coin in question in pic just a pic I had in my phone ! But thanks for answering a question with a question !!!!
Don't worry about what one member says, this IS supposed to be a friendly forum. The absolute worst you can do to yourself is to not ask any questions.
Cleaning coins is an interesting field to study, if done correctly you can definitely improve the coin. NGC has a department dedicated to this: https://www.ngccoin.com/ncs-conservation/
Then trust me on THIS - as long as you self-describe as a "Newbie", as in your handle, the best thing you can learn about cleaning coins is "DON'T!" Cleaning coins is an EXTREMELY advanced aspect of numismatics, and you're putting the metaphorical cart WAAAAAAAAAY in front of the horse. Everybody wants to jump to doctorate stuff before they graduate from high school anymore. SHEESH!! If you're GENUINELY attempting to learn numismatics, see this: https://www.money.org/diploma-program
The coin in question is not a BU by any stretch so I'm sure cleaning it will not hurt. If it were a mint coin I certainly wouldn't be asking the question !
If you truly want to learn @Newbie69 , just read, ask questions, get to know other numismatists, join clubs and attend coin shows! With cleaning, just pick out coins of no value with corrosion or damage or something and practice on them. You certainly don't have to go to the lengths of a Diploma program to learn numismatics.
There's your first wrong assumption. Cleaning DOES hurt coins' value, even when it starts low. Yes, some practitioners can get away with it. I recommend at least Weimar White's book on "Coin Chemistry" before you just dive in.
