Soak in acetone again, repeat as necessary until gunk comes off. Shouldn't affect the luster from what has been shown so far in your comparison photos.

I don't think the spots will come off with out damaging the luster. I should have said I would have to rub with something like a q-tip and that would do some damage. I'll keep on soaking and see what happens. Had to look up UNC Details. That's why I bought it. It looked uncirculated from the pictures. Didn't know if I could get the glue off. |

Back into acetone it goes.
Use your finger/fingernail if it needs some help getting off. Yeah, yeah, it's taboo, but heck, works great. I do it on nicer Ikes all the time... use my finger to get the residue off, then back into the acetone to get the oils off.
This coin will probably need a dip as well, once all the residue is gone.

Don't use your fingernail. The tape residue should melt with further soaking in acetone. If you don't have access to an air hose, get a can of compressed air that you'd use to blow the crud out of your keyboard and use that to "move" the remaining, presumably loosened glue.
If that fails ... a high tack masking tape will more than likely remove it. You may even want to try that first.
That's a pretty serious die crack ... and not a scratch on the obverse.

Don't use your fingernail. Soak, and then soak again if necessary. also compressed air if necessary as stated above.

Sometimes but not always. If you look closely, it continues counterclockwise through the denticles all the way to nearly the 8 o'clock position.

Don't touch it with a Q-tip. Better your fingernail or a toothpick. That's a rare 1921. It's a tremendous strike, and a 1921 with fields even resembling PL is a rarity. Devote the time to a patient acetone regime; don't be afraid of multiple soaks of 24 hours or more. There aren't many 1921 specialists, but every single one of them will see what's different about this coin. It's worth the best conservation effort you've got. I'd pay a premium for this one. After you get rid of the goo.  |

I was hoping you'd weigh in on this one SD. I know you're a 21 Morgan guy.

Wouldn't you be worried about burnishing the luster using a tooth pic?
In my vast two weeks worth of experience I have tried a wood tooth pic soaked in acetone on another Morgan and it seemed to leave a shiny spot.

No, I'm not worried about a toothpick. With a toothpick, you pick. With a Q-tip, you rub. Only one of those solutions involves grabbing something and immediately lifting it off the surface; the other involves grabbing that something and rubbing it on the surface. The difference is huge in the numismatic sense because the whole point is to get stuff away from the surface, now.
Any application of a tool to the surface of a coin must always be weighted against the consequences; leaving a mark is fatal. It's that simple. I feel that in this case, the use of a picking tool (toothpick; very much preferably a rose thorn because they're so sharp) might be the difference between getting the coin clear or not, and I will always advocate liquid-only contact before ever suggesting a tool. I may be proven wrong here, and the coin won't need a tool; I hope I'm wrong. This coin is worth treating in the least-intrusive manner, because it's a relatively rare strike of an issue struck in the millions. This one needs the best care. There aren't many, and that number isn't going up.

Thanks Dave.
It will be soaking until I don't see any more progress. Could be a while. Then I'll try the tooth pick.

It doesn't look truly PL to me, just flashy, FWIW, so given that, and the bag marks, I think it's probably something like 63spl at best.

Remember ... scratches don't add value. I'd no sooner use a toothpick any more than than I would a wire brush.
The contaminate is tape residue. If it's mucilage ... old "hide glue", warm water may be more effective than acetone. Even if it's a more modern glue, It can be removed without anything touching the surface of the coin. Using thorns, toothpicks, and even q tips ..invites scratches ... some larger than others ... but all equally undesirable.
Air is still the best tool. The effectiveness of masking tape will also amaze you.
Bet Dave won't want it near as much with scratches on it.
