I just got this in, and didn't do too bad on it, it looked RB from the picture. My question is this, the dark on it appears to be from fingerprints in hand. I purchased it for an error set I am putting together and plan to put it in a Dansco, it won't be slabbed until time to sell, which could be years and years from now. Should I do anything dip-wise to keep the dark areas from getting any worse prior to placing it in a Dansco album? For now, I have it in a 2X2. Thanks for any help or advice! Feel free to offer a grade opinion on it if you would like! Rob

I would leave it alone. Copper and chemicals don't mix, and any type of dip will likely destroy the coin. It looks to be a nice, original coin, and should be stable. Check the spots (like those around Abe's head) for any visible surface contaminants that may need to be removed. Keep an eye on it and if any contaminants are causing problems, acetone it. Again, it looks like a nice coin and it should be just fine.

Nice looking coin and great example of this DDR.
You have to be real careful with these coated Zincoln's because if there is any break in the skin, these will eventually (and quicker than most think) dissolve from the inside out leaving only the shell. Carefully examine your coin to be sure the corrosive spots haven't eaten thru the skin. If so, I would sell it and look for a clean example that will not disintegrate.
If the skin is intact, I would try soaking this in mineral oil for a while to help get rid of those corroded areas before they get any worse. When you take it out of the oil I would leave a little of the oil on the surface to help protect it and help it keep its color.
Hope this helps and ...
nice coin

I don't think any kid of dip would help.

You would have to test it with pocket change first but Acetone might get that black off without doing too much to the rest of the coin. It does not affect other metals but it does effect copper a little so I would only do short dips.

Wow, after reading the responses, I looked a little closer myself at the pictures, and do notice that there may be some possible trouble spots. I literally just got this in the mail today and took a few pics under different lighting without using any color correction etc. (ie. no photoshop etc.) You cannot see much in hand (as far as trouble spots), other than the couple very small spots like on the T in trust on the obverse. As everyone knows, pictures seem to blow up blemishes, but I will go over this some more in the morning and probably take a few more pictures a little more carefully to get a better idea before I do anything. I really appreciate everyones responses so far. The one thing the pics I posted don't show is the amount of red on the coin and maybe a little more context, but I am glad you all brought the possible corrosion issue to light, as this will be a 20-30 year Dansco coin, and I don't want it to be eaten up at that point! Thanks again for the responses so far! Rob
