Can Ugly Dark "Toning" Be Safely Removed?

Thanks again for the replies and insight, here is a couple of images of the 1930 ANACS MS63 FH (I know, I need to work on my lighting);

Have you ever heard of MS70, I've used it on some of my Franklin's and Silver Eagles. If used properly as the directions state, I would see this as a better alternative if you must.
Is the toning something that was their when you bought this coin, or did it develop over time. I guess what I'm trying to ask is do you know whats behind the toning. Cause if you bought it like that god only knows what it'l uncover. From the looks of your photos it looks pretty smooth. I would recommend the MS70 if anything. If you do decide to go for it, please post pics.
Good Luck. And I'm with the Majority when saying the toning doesn't look bad. But If it were mine I'd have to remove it. Unless your using ahhh I can't think of the name...... The boxes that have a lining of copper in them. UUUhhh I hate when this happens. You know the boxes that stop sulfur from getting to your coins. At least if you keep it in something like that it won't continue to spread. At least I don't think it would. Sorry I couldn't remember the name.

I think I agree with Bizybackson, and would leave it. I would buy that over a cleaned one :)

I got this one on the bay with one of those infamous "less than clear image", I thought that there was a lighting shadow covering the top portion of the coin...I was RIGHT & WRONG, it was a shadow, but not from the lighting, it is from the toning. It's an older ANACS holder, but I do not believe that is why it toned the way it did. I will post the reverse tonight, I got too wrapped up in obverse last night.

I have another TYPE II FH coming and I am going to release this into the market for someone who can appreciate her beauty.

Thanks for all the replies!

Best for all concerned. This coin is a very poor candidate for a successful dip.

Here is the reverse;

Yes, I am going to leave it "as is" and sell to recoup the expense from the 1917 Type II SLQ that I just got.

One thing about messing with any coin in cleaning is if it is yours, you can do as you want, like, etc. It'a yours. And if you do not PLAN on reselling it, so what if it gets ruined. HOWEVER, that is always one of the things to remember. You may not plan on ever selling any coin, but what IF. And then too, someday someone else will get that coin and would probably be thinking WHY did he do this.
