Wheatie toner - wow! How to remove tape residue

So I have a ton of those old framed sets. Ya know the ones, silver story, westward journey (buffalos), 20th century type set....etc...
Anyway, most of the silver, IHC's, V nickels, Buffalo nickels, are all polished to a shine. I decided to replace a lot of them so I dug out the frames. I grabbed the "WWII emergency coinage" frame and saw this Wheatie in there.
I can't even come close to capturing the color on this bad boy. I have some toned wheaties, but I have never had one that has target toning like this. Is this common?

Anyway, I popped it out, and the reverse has the sticky residue from the tape on the back. It looks to have awesome blue colors under it.
Can I remove this with Acetone? Will it remove the toning? Or what? Thanks!

Acetone should work. Nice coin BTW.

 

And, yes, "target toning" AKA album toning is common on Lincolns.

 

I replaced all the nickels with MS and same with the lincolns. Back in the frame they go, and into storage. Curious to see what happens.

Gmaster - thanks, I will give it a quick soak.

 

Nice one. As stated, acetone will take care of the tape residue without any damage to the coin. Just make sure you use pure acetone and not a product like nail polish remover that contains acetone as well as other chemicals that can harm the coin.

 

Note to self *make sure the cap is tight on the acetone can*
I just went to grab it, it completely evaporated. lol

 

LOL...I've done that more than once.

 

lol...i try to stay away from the whole cleaning coins thing!

 

I add white vinegar 1 teaspoon to 10oz of acetone in a good sealing glass bottle and that help too,it won't remove the toning but it will keep carbon spot from returning if there is any.
plus you need also to dip it in some distilled water after the acetone to remove the acetone.

 

I'll yield to BadThad and others on copper chemistry issues, but adding vinegar to the bath seems like a terrible idea. Even in low concentrations, it's bound to attack the metal, at least to some degree. And as the acetone evaporates, it'll leave the vinegar behind, getting more and more concentrated.

If you use pure acetone, there's no need to wash with distilled water. Acetone evaporates a lot more quickly than water, leaving nothing unless it had impurities to begin with.

Doug, about the "weird colors" thing -- were you saying in an earlier thread that you fish coins out of the acetone with your bare fingers? If so, the acetone would grab oils out of your skin, and leave them as a (very thin) deposit on the coin.

 

I been adding white vinegar since the 60's but the key is keep above 10-15 to 1 part any larger amount will affect copper & bronze if u dip it in for longer the 1min it will affect it 4 sure.with that low amount of vinegar it will dry just like acetone.but acetone is traceable if you plan to have it graded vinegar take the carbon & the trace acetone off the coin after a bath in distilled water +pat dry.
here 2 I did 1995-P DDO & 1944-D that was done with vinegar&acetone about 1-2years ago & Pcgs graded it to.
but now Pcgs has that coin sniffer & I am not sure it it will be pick it up with that new machine

 

Acetone should do the trick. It can give some red copper a little pinker hue but it seems to work well with brown or toned copper.

Vinegar may appear to help the coin but it is acidic, like lemon juice, which means it will attack the original Mint finish. Surely some such coins have slipped past TPG's but if they suspect it has been "juiced" the coin will be body-bagged.
Lance.

 

I did an acetone bath. All the residue came off. But so did the toning ill post some pics later for your viewing displeasure.

 

Did you use the vinegar with it?

 

I would suggest you IM the PennyLady for advice. You could also look into conservation services by one of the main graders.

 

Yikes. Ouch.

 

You may have gotten away with this in the past, but it was pure luck. Vinegar's active component, acetic acid, immediately attacks the coin's surface. If you dilute it a lot and don't apply it for long, it won't do too much damage, but it won't do too much good, either.

Don't use acids, including vinegar and citrus juices!

 

I did not use vinegar. My feeling is maybe the toning was mostly from finger oil when it was pushed into the cardboard. I don't know. It was a good test piece.
Its too nice outside today for me to be bitter!
