Try benzene. It should not damage the coin.

how long did you put the coin in acetone? it may need a longer soak and some very gentle poking with a toothpick. by the way wow! nice coin.

A lovely find.  Quote:
KevinH, that is not a gouge under "GOD", it's more of that black stuff.
Acetone does not remove it. It is sticky and can be scraped off with a tooth pick. If the stuff is ornery, acetone could take days to pull it loose. If you can shove it with a toothpick, a TPG would likely Detail grade the coin because of it. Yet, if you successfully remove it (I think acetone ultimately will), the surface might end up looking spotted because what's under the crud didn't age as the rest of the surfaces did. That gets you a Details grade too. It's the "rock and a hard place" moment so common when deciding whether to conserve a coin. |

I agree 100% . At this point, that is such a desirable coin (and one of the three keys to the series, along with the High Relief 21 and the 34-S), if it were MINE I would go ahead and send it to a TPG service. And I might buy that off you after it gets slabbed!  I've got the other two "keys" and that coin you have looks like a real beauty if the black spots go away. And if not, I could still live with it, and I'm sure other collectors could too  |

As to grading, also remember that the right shoulder of the eagle is just as important as the brow hair.... and they both look to be in great shape on your coin . I'm not expert, but the Details are at least high AU if not low MS. I am interested in what others thing about the grading, ignoring the black crud spots. |

From a grading standpoint it's one of those I wouldn't choose between circulated and Mint State without the coin in-hand. My guy says it's circulated slightly. No_way I could keep my paws off this one if I owned it. I'd have to know if I could remove the spots. Kids, don't do this at home.  |

Here are the most accurate pics I could take. These look really close to what I see with my eye. I soaked it in acetone for about 20 seconds. Then rinsed it off with distilled water. Can I soak it longer? I would send this in to get slabbed if I could remove the spots. What are your thoughts on TPG "restore" service? At about 4% of value, that might even grade it higher to put more money in TGP pocket We both win.  So, big question is how long can I soak it in acetone? Also, the Rev. USA and EPU seem worn or is that light strike common for Peace dollars? Thanks   Edited by One50

At least 24 hours. Acetone doesn't react with metal

I wouldn't mess with it any further. It's a lovely coin.

I put it in acetone over night and the black crude didn't budge.
I'm going to take it to my local coin club meeting this week and see what more experienced eyes can tell me.
I would love to get that crud off.

Just leave it alone man, you aren't going to raise the grade by further monkeying with it. If it's on there that good, you'll end up pulling off the surface of the coin with the crud and then you'll still have a less-than-perfect coin. Obvious signs of cleaning the coin will get you details grade faster than some black spots for sure!
Send it in for grading and get it slabbed and enjoy your good fortune at finding a 1928 in a junk silver pile.

You might also want to try Denatured Alcohol. I don't think silver can get carbon spots (that's reserved usually for CN type coins). I would think whatever that is (as long as it's not toning, which it might be now) should come off with the appropriate solution. If it is toning, then maybe do a very light dip.

I'm bumping this topic back up. I have a couple coins going to TPG for my 1911 short set. I'm sending this one in as is, black spots and all. I simply need to know :) Worst case is details and it's sealed in a slab for protection. I'll let you know the outcome in a few weeks. |
