I would urge you not to clean coins. If you wish, you can click on the link below, and read an interesting article on cleaning coins. LINK(click)
cleaning wow!! thanks so much for information I will not touch them I will go to a coin collector place this weekend and see what he can do for me thanks again sasha
Awwwwwwwww - that means you'll have to break it out of that MS66 slab 'Course it will be bright n shiny when you're through
I guess its a slight difference of a multiple x value between grades, and crazy color like that dazzling jewel.... It commands a premium to the tone heads!
Yeah I know. I was just tryin to give ya a hard time QUEENKOIN Being all serious and no play makes GD a dull boy
Can someone tell me what the small black spots are that we sometimes find on coins. I have two pin head size black spots on the reverse of a 1964 Kennedy Half. I know the horror stories about cleaning coins, but is there a baking soda trick or something similar out there that I can try? Nothing harsh mind you, but it would cost more than I would like to pay to have it proffesionally cleaned. Will the black dots/spots increade in size? Thank you, Jim
Without seeing the spots, it is a little hard to say. Often silver will turn black due to oxidation. Other factors can change the color. Silver, like copper has ill effects when handled and exposed to certain conditions such as high humidity. A small amount of baking soda mixed with distilled water will remove most spots. Take into account that it will leave telltale color on the coin. Never do this with a coin of value.
Ahem..... well, actually, brown spots/ toning on silver is oxide while black or gray spots/toning is sulphide. Brown toning can happen from exposure to humid air or water while black toning usually comes from contact with a holder that isn't sufficiently inert or from skin oils or other contaminants staying on a coin in a holder for a period of time. Yeah, I know. That's a nitpicking response. ;-)
