how to get rid of sticky tape residue on my coins

People keep saying that it's fish oil, and it keeps not being true.

In other forums, people keep saying that it's vegetable oil; that's not true, either.

It's not animal oil. It's not vegetable oil. It's MINERAL oil.

If you don't believe me, go look on the WD-40 website yourself.

But as long as they won't say what the 10% "non-hazardous ingredients" are, I wouldn't put it on my coins.

Whats a good way to get rid of the green and black corrosion on a wheat cent? I'm not worried about scratches, because if I leave the corrosion the cent its going to eat it away anyways.

 

Verdicare. If that won't do it, nothing will (at least not without damaging the coin).

Depending on the state of the corrosion, it might already be too late to avoid damage. But, Verdicare won't damage the coin in itself.

 

Depending on the severity, this is the only method I would recommend. The inventor is BadThad on this forum, and I have used this myself.

Thanks for the advice guys!

 

I had a 1968 Kennedy Half my grandmother gave me that had some old dry tape residue. An overnight soak in acetone got rid of most, leaving a subtle remnant. A couple weeks with the pocket pieces got rid of the rest.

 

Unfortunately my coins are UNC error coins so I can't do that

 

Let's get chemical. Since your coins are UNC, you REALLY don't want to rub them at all. We are then left with solvents. Acetone is usually great, but sometimes it doesn't work. In solvents it is usually a case of polarity. Since acetone is somewhat polar, you should try a non-polar alternative. Most common would be hexane or toluene (or xylene if this is too stinky). Mineral spirits might work. Failing this, the only other thing I could think of would be to attack it with acid or base, and that might hurt the metal. BTW, here is a listing of polarities: http://macro.lsu.edu/howto/solvents/Polarity index.htm

 

So just dip it in xylene or soak it?

 

I haven't used xylene myself, but unless the xylene is contaminated, I'd think you could let the coin soak in it forever without damage.

 

Always follow the polarity ladder!

This is the best answer. Use the same precautions with Xylene as acetone (no open flames, good ventilation, don't guzzle or whiff it, and use a non-plastic container).

 

ok ill give it a shot and report the results

 

I kind of like it that you classify ketchup as a harsh solvent...I always thought it was a vegetable.

 

Just as an add-on, it is of utmost importance that the cleaning solvents you use are pure and fresh. Had a REALLY bad experience with some bad xylene I should post sometime. Additionally I would try and let any excess solvent drain off or wick into an absorbent material rather than dry on the surface.

 

Bad xylene? First I've heard of that in 30 years....please explain, very interested.
