I have two older copper coins in great shape but they have a few spots of blue corrosion starting. I want to take it off but figured I would check here before I did something to ruin the coin.

any ideas what I could do without compromising the coins value

thanks in advance

    Fix No but slow it down yes. Need a pic maybe if it's just starting.

    You can't uncorrode copper---it's not reversible.

    You can arrest it from getting worse, but you can't reverse it.

    Soak in olive oil for a few months to a year.

    I've seen quite a few IHC's where spots have been removed and it hasn't influenced the value...... image

    You may wish to take some pliers and squash your staples flat.

    I would first try an acetone soak (agitate it twice daily), followed by alcohol rinse and hot, running water. If results not as desired, I would then try the EVOO soak....long process, but can work on some things...Good luck, Cheers, RickO

    You might try pushing those spots off with a toothpick. The classic device is a rose thorn. That could be lose stuff that is sitting on the surface.

    I have had a lot of success with Coin Care and a few Q-tips. Always need to carefully inspect the coin's surfaces first -- if
    the corrosion has eaten into the surface, it is too late. Don't be in a hurry.
