    I've heard of people using WD40. The surface may be pitted from damage of the green stuff.

    From my limited experience getting rid of the vertigre, will leave spots, pits, and or discoloration, but maybe some one has a better way..... image

    So I guess wanted to send this to be graded would be crazyimage I have thoughts of sending it to ANACS along with the 1940 Irish penney. I must admit to all I have become shy about sending things to be graded. I guess I don't want to be disappointed in the truth of how bad off they are. I think they are great coins myself....I don't want some schmola grader raining on me picnic....LOL!!!!!!!!!!image

    I wouldn't send it off. Your 1940 penny has a rim bump, as I recall, so I would keep that one raw as well.

    I just started using WD-40, with decent results. I have also used Vaseline in the past. Take a wooden toothpick and some Vaseline (or WD-40), and work at the crud with a toothpick. As others have mentioned, you may have some pitting where the crud was, but you CAN improve its appearance.

    If ANACS considers the corrosion to be "active" they won't slab it. You might want to call them and ask about their policy on slabbing coins with green corrosion visible.

    Why hasn't anyone suggested the olive oil treatment (which I've heard several members recommend) to remove the verdigris?

    Because I personally do not like olive oil. It leaves a sticky residue. Mineral oil is better, IMHO.

    I recommend MS70 for verdigris.

    Yes, but doesn't MS70 do weird things to copper???? Okay, no grading of these two beauties. They will be for my own personal enjoymentimage

    If you rub the coin after it's been in the MS70, then the toning will be removed as well, and the coin will look funny. But if you just soak it and wash off the residue, the coin will look fine.

    I've never heard of using MS70 on copper, for verdigris. Will it neutralize the verdigris, or remove it? Naturally, if verdigris is encrusted, it will leave pitting behind, but that looks better than green junk.

    Olive oil is painfully slow, and for deep encrustations it would take years to come off, if ever. I've found olive oil to be most effective against young verdigris (not yet encrusted) as well as other "claggy" junk/debris between the letters and details of the coin. Olive oil also works to remove PVC contamination. You can remove the oil with acetone, with no harm to the copper (as far as my experience has been).

    I've heard that Blue Ribbon will work on verdigris. However, I've not tried it yet.

    Try soaking it in xylene for 8 hours or so. To do so, you'll need to get a glass jar with a metal screwtop. Try using a widemouth Mason jar or somesuch. The reason for the glass and metal is because the xylene will eat throught any plastic, and you'll need to keep it from evaporating.

    Just let it soak (nothing magic to 8 hours)......when you remove it use xylene wetted cotton puffs to "blot" the copper surfaces. Keep blotting until no greenish-black residue comes off anymore. After this, use a xylene wetted Q-tip (use only Q-tips with paper stick or wooden sticks). Apply pressure against the verdigris area gently but forcefully rolling across the verdigris. By now you should see some improvement....

    Now, go with a "soak" in the WD-40 or Blue Ribbon conditioner, and leave it on for a day or so, then repeat the xylene cotton puff/Q-tip treatment to remove more crustations or whatever.

    Neither of these substances will damage the coin or harm the color, just be careful with the Q-tips....roll the tip, but do not push it forwards and backwards.

    Use the xylene either outside or in a well ventilated area....I'm SERIOUS!!!

    Good Luck.
