21' Peace Dollar. Not sure what to do?

I came across this in an antique store today.
As you can see below the reverse has a green (pvc) and pink (?) corrosion on the reverse.
What would your restoration process be?

I am thinking hot distilled water soak followed by acetone for possibly a day.
I do not have access to a dip or a coin restoring product at this time.

Any thoughts?

acetone dip...

 

I would dip it in silver jewelry cleaner from Walmart. Swish it around for a few seconds and rinse with clear water. Or try Acetone.

 

I will give this about an hour. That corrosion needs to be removed.

I will do, my thinking of hot distilled water is to remove some of the dirt and grime from the coin first.

 

Not a bad idea I give a lot of my raw coins the boiling distilled water treatment. silver PVC gets acetone dip, for copper i use Verdi-care, but VC can be very hard to come by

 

Wow , Acetone . They put that on everything . LOL

 

one of the few thing that desolves PVC from coins and doesn't automaticly make it a "cleaned/details" coin as using most "silver/jewelry" cleaners would do...

 

I know but all the precautions scare me . Wearing gloves , ventilated areas , etc. I don't know if I can use that with my lungs . What kind of mask can I use ?

 

I have lung issues myself, I usualy do any acetone work out on the porch. I drop coin in glass leave it alone for a bit, remove coin, pour used acetone on cement driveway to evaporate. Mostly no mask other then lil basic mask most of us presently wearin out of the house but I do try to stay upwind at all times those fumes nasty nasty stuff for me

 

Out side is fine, stay upwind if you can. Acetone will dissipate (easy to dispose of) so if you have something to cover it with you are better off.

 

I'm not sure this coin can be helped. It looks pretty far gone.

 

I was gonna say the same thing but didn't want to sound like a " Debbie Downer". LOL

 

I am not disagreeing with you. but for 27$ it was hard to pass up.
I am more interested in stopping the corrosion.

 

That's called "Conservation" as opposed to "cleaning"

 

You may be able to stop the corrosion but it may look terrible, $27 not bad. If you learn a lesson it's not too big of a deal! Here's what I would do, first day soak for 24 hours in Hydrogen Peroxide. Next day, hot distilled water, maybe even boiling your choice! After that, something should have been removed. If there's still crud on it go to Xylene or Acetone soak, check daily after two or three days soaking you'll see what you have left. At that point you can use a silver dip like Tarnx or the stuff in the pic, if you choose to. You may not have to after the acetone or xylene soak. good luck!

 

Wow !! That's a big container !

 

Never heard of this method.
Can you tell us what it does and how it affects the coin?

 

I don't trust hydrogen peroxide on coins. Hydrogen peroxide is an oxidizer that can cause a coin to...duh...oxidize. Acetone isn't that bad. I would put some acetone in a container that will hold the dollar and allow it to be totally immersed. Cover it and let it sit overnight or longer. I fish it out with my fingers and blot it with a tissue or toilet paper. You can replace the acetone and repeat if you think it helps. My next move would to put it on a cloth in a sink and let very hot water from the tap run over it for 1/2 - 2 minutes, turn it over and repeat. Rinse with distilled water and see if it helped. None of the above should damage it.

 

I'd suggest at least 48 hours in cool distilled water before anything else. I've had some luck with acetone, but you don't need to soak it for long, and should use a distilled water soak afterwards. Somewhere, I have a thread I started about the effects I had with various methods on cleaning some "rusted" Morgans (they'd been stored next to a leaking iron pipe & had some crusty adhesions).

 

Yes, just found out about it a couple of months ago but I've used it quite a bit on Tokens and Medals. You can use it on coins as well, it may be an oxidizer as @Kentucky mentioned, idk but 1 day isn't gonna affect anything at all. I've had really good results with it. Another thing I've done is put a coin with distilled water in a plastic jar and shove it in the freezer overnight. Helps to get rid of the dirties! You can google both ideas as that's where I got them from!
