I didn't know yhou could damage coins by putting them in flips that contain PVC. Now I have 158 coins that have been sitting in these flips for about 2 years. I don't see damage but figure an acetone bath for each might be a good idea. Is there some way to do this quickly? Can I put more than one coin in the jar at a time?

Do you need to rinse your coins with distilled water after their acetone bath?

First do not use fingernail polish remover. It has oils that will discolor the coins. Try soaking in acetone on an test coin, it will totally evaporate. If it leaves a residue try some 200 proof ethyl alky. It might remove anything left on the coin, hopefully. It's worth a try. Use these in a well ventilated area as neither is good to breathe.

Thanks. I read one should rinse the coins with distilled water after the bath.

The coins may all ready be ruined so if you want to try the distilled water go ahead and try. Just don't rub the surface as that will show up as a cleaning. The whole thing is to not take away the natural mint or circulated finish.

I did 87 Buffalo's that had early stages of PVC damage at one time in an acetone bath. The first time I left them in for about 15 minutes and the acetone turned a greenish grey. I took them out and soaked them in distilled water for another 5 or so minutes and let them air dry on a clean towel. Then they went into another fresh container of acetone for another 15 minutes followed by a distilled water rinse. They came out looking just fine.

Thanks for the help. Cleaning 158 coins will be a chore.

PVC flips will not damage coins in the short term, but in the long term, you are looking for trouble.
I had about a dozen bronze Victorian full red uncirculated 1/4 anna coins from India, with a date range 1858 to 1900.
They were in Mylar 2x2's in PVC album pages for about 10 years.
In that period, ALL of them went VERY dark, before I woke up to myself.
They were re housed in replacement 2x2's, but in archival quality clear album pages.
Nevertheless, the damage has been done, and it IS permanent.
Acetone in this case, is of no use whatsoever.

it's all semantics, but cleaning has a negative connotation to most coin folks. 'Restoring' makes it sound better. =)

Rinsing with distilled water is not necessary but you should do a final rinse with clean acetone after a soak. Rinsing with water can potentially leave water spots on a coin, most problematic with MS and proof issues, not so much so with circ coins.

52Raymo: Mylar 2x2's are fine, I continue to use them.
In BOTH cases, I was / am using Mylar 2x2's. THEY are NOT the problem.
The long term use of PVC album pages IS the problem.
I replaced the Mylar 2x2's with new Mylar 2x2's, and CHANGED the PVC album pages for archival quality album pages.
In the first storage system, the coins were darkening, despite being housed in the Mylar 2x2's.
