Can this haze be removed?

It looks great while sitting in acetone but pull it out and it goes right back to haze.

    I don't guess I've seen haze on business strikes. I know I have tried to remove haze on a proof with no luck. Acetone will most likely do nothing about haze. I tried ez-zest on mine and the haze still could not be removed.

    Maybe it’s time to experiment with other chemicals. My guess is no to removal but never hurts to ask.

    Be careful with acetone on cents.
    Real quick dips only. Acetone and copper are not friends.
    MS 70 might help but it too can have some reactions on some cents.

    Some coins are just plain "Interesting"

    Maybe, but copper can react weird with chemicals. If it's not a cent you really care about, then go for it.

    Yea i’m not too worried about negative results because I don’t think it would grade very well with the haze anyway.
    If I happen to get any positive results I’ll surely get back.
    Thanks folks!

    Acetone will not harm copper, however, the organic residues sometimes found on copper can leave a cent looking radically different upon use. That haze is obviously not organic if acetone will not remove it. Harsher chemicals could attack the copper, or perhaps, harsher chemicals (no idea what) have caused the 'haze' effect, it now being a surface condition rather than a deposit. Cheers, RickO

    Yes, acetone will not react with metallic copper (or zinc) in any manner.

    The pardon is for tyrants. They like to declare pardons on holidays, such as the birthday of the dictator, or Christ, or the Revolution. Dictators should be encouraged to keep it up. And we should be encouraged to remember that the promiscuous dispensation of clemency is not a sign of political liberality. It is instead one of those valuable, identifying marks of tyranny.
