Stand clear!! I'm going in to try my hand at my 1st. acetone bath.

Before:

After:

ANACONDA · July 5, 2007 5:54AM

What do you hope to accomplish? Removing haze from a coin?

Cladiator · July 5, 2007 5:55AM

pvc?

Steve27 · July 5, 2007 5:56AM

First get rid of the distilled water and alcohol; they're not needed.

hiyosilver · July 5, 2007 5:56AM

I have a Morgan w/a small dot of green in the headband and a few small spots of crud that I want to remove before I send it in for grading.

AUandAG · July 5, 2007 6:05AM

How about a before pic and an after pic?

<<How about a before pic and an after pic?>>

I do have a before pic and it shows the area on the obv. I want to take care of. I'll post the before and after when I take the "after " pic.

<< What do you hope to accomplish? Removing haze from a coin? >>

Have any good tricks?

hiyosilver · July 5, 2007 8:53AM

UPDATE: Looks like the black crud has all but disappeared and the small green dot on the headband has reduced in size to a speck. I think I'll let it soak overnight and see how it looks then.

tmot99 · July 5, 2007 9:36AM

It shouldn't take overnight. I'd suggest a Q-tip soaked in the acetone and a light rub. Careful not to put scratches on the coin.

LindeDad · July 5, 2007 11:13AM

Also if the acetone is in a open container it will evaporate and leave a film on the coin.

nesvt · July 5, 2007 11:16AM

I usually use a closed glass jar. If stuff has come off and there's still a speck, change the acetone. It needs some fresh stuff.

DieClash · July 5, 2007 11:25AM

<< Also if the acetone is in a open container it will evaporate and leave a film on the coin. >>

I soaked this one for 72 hrs! Although not much changed after the overnight bath, I discovered the film from evaporation after the 2nd night so with a fresh bath I gave it another 24.

Before is the image on the left and After appears to the right.

I'm curious to see the results on the Morgan that is the subject of the OP. Acetone is very effective on certain foreign material contaminants IMO.

7Jaguars · July 5, 2007 11:53PM

Yes, I too use the Q-tip but let even it soak for a few seconds before gently working the area with it. I have checked afterward with 30x dissecting scope and not seen any hairlines. BTW, use the real Q-tips and not faky knockoffs as it seems the cotton tips are a little better on them, at least in my experience.

If the leftover dot still bothers then you might want to soak for 30-45 minutes in lemon juice and then wash clean with mild detergent and rinse again with tamp dry using a clean white cotton towel. That does not seem to bother the lustre too much although may remove some patina (much milder than the dips).

hiyosilver · July 6, 2007 1:25AM

I didn't use any Q-tips or rubbed the coin in any way.

Looks much better in my opinion.

IMO Xylene (Xylol) works better than acetone and is not as volatile. It is hard to get though.

tincup · July 6, 2007 1:34AM

Use caution if you are using xylene.... it is not good stuff for your body. Not good to breath in or let get absorbed through the skin.

Acetone is probably a safer (for your health) than xylene....

7Jaguars · July 6, 2007 2:22AM

Uhhh, a deadly poison it is. The pics are nice, looks pretty good in the after. I suspect that is not a PVC spot though. It looks to be oxidation but that having been said occ. the acetone solution will loosen mild oxidative or verdigris changes.

Please do avoid xylene or xylitol or ANY benzene products (or oven cleaner for that matter). If it is not an ordinary solvent and you see it, ask question or research it first before using.

DJCoinz · July 6, 2007 2:46AM

Nice B & A.

jmski52 · July 6, 2007 2:48AM

Neither one is good for you, by ingestion, skin absorption, inhalation or any other means! Both go through the liver. Both have a known toxicity. Both should be used with neoprene gloves in a very well ventilated area. Both are very flammable. Handle both with great respect.

Shamika · July 6, 2007 3:00AM

Take a q-tip or toothe pick to the green speck. It shouldn't be a problem on circulated coinage.

tmot99 · July 6, 2007 3:12AM

You better tell all the women in the world not to use nail polish remover as most is mainly acetone. I agree that a LOT is not good, but a light rinse is not going to do much. It is, however, flammable and you should be in a ventilated area.

Here's what I use:

Allows me to squirt acetone right where I need it. I usually hold the Q-tip and coin in one hand with the Q-tip in front. Therefore, both get soaked with acetone before a light rub with the Q-tip to remove PVC.

7Jaguars · July 6, 2007 3:40AM

On order of toxicity xylene and derivatives is literally hundreds of times more dangerous. I can not say that I am confident that neoprene would not break down with these.One thing about gloves is that you lose the sense of touch and are much more likely to drop coins or have them slip,and neoprene is not going to be as thin as the ordinary latex gloves which will definately dissolve with the acetone. fortunately acetone is a substance that does not go completely unrecognized by the liver as opposed to the other...

rgl1345 · July 6, 2007 3:50AM

Boy, this is what I like .....Ton's of good solid info and personal experiences.

Thank you!

Writersblock · July 6, 2007 10:46PM

<< IMO Xylene (Xylol) works better than acetone and is not as volatile. It is hard to get though. >>

I find I prefer acetone. I like the rapid evaporation and I often fird that the xylol is not a pure as the acetone tends to be. I've never had problems finding either one though. You probably won't find the xylol at Wal-Mart but I've never had problems finding it in the paint dept of a good hardware store.

After looking at the MSDS for both a few other sources I would say that acetone is probably much less toxic but it is much more flammable. Both will burn, but I find it much more difficult to ignite xylol. Acetone on the other hand can be a flash fire and explosion hazard.

FLBuffaloHunter · July 6, 2007 10:54PM

I find acetone tends to leave a haze on coins after they have been dipped in MS70, which is why I prefer Xylol. I use lab grade chemicals from a medical supply, not hardware chemicals that often can leave residues.

tmot99 · July 6, 2007 11:15PM

<< I find acetone tends to leave a haze on coins after they have been dipped in MS70, which is why I prefer Xylol. I use lab grade chemicals from a medical supply, not hardware chemicals that often can leave residues. >>

That very well may be a reaction between the acetone and MS70. Do you rinse off the MS70 with water first? If you are just rinsing off the MS70 with acetone, bad idea. I very rarely use MS70 so I don't know all that it can do. The only time I've used it was on some brass medals that had die from a ribbon on them. The MS70 took it right off. I then rinsed in water. The final step after the MS70 was removed was an acetone rinse with left no residue and no haze that I could see.

FLBuffaloHunter · July 6, 2007 11:28PM

Yes, I use MS70 to remove haze from silver Proofs which it removes great. I then rinse well with distilled water, and then dip in Xylol to remove any residue. I find Xylol is a better solvent than Acetone and is easier to work with since it evaporates much slower.

hiyosilver · July 7, 2007 1:06AM

I worked with xylene as a machinist a long time ago. Some nasty stuff!! I'll stick w/t acetone for my coins , at least for now.

fc · July 7, 2007 1:41AM

bah. acetone on a coin that barely needed a dip. to what? remove
a tiny speck of dirt. more coin doctors in the making.

just cannot resist messing with old stuff huh? hope to improve things
huh?

lol. you guys never learn.

did i see pvc mentioned in this thread? nope. (lol a dot of green)
before he sends it in for grading. funny. that common Xf coin in plastic?

seriously. better ways to spend money.

BigDaddyz · July 7, 2007 1:46AM

I'm surprised no one has raised the question as to why someone would submit a low MS morgan from 1921

hiyosilver · July 7, 2007 1:47AM

<<did i see pvc mentioned in this thread? nope. (lol a dot of green)

Actually, yes it did have a couple of small spots of green ( pvc ), now it does not and should holder instead of NET grading or body bagging because of it.

As for why holder it.......maybe it's a rare variety.....

7Jaguars · July 7, 2007 7:38AM

MS 70 and acetone have very different properties and do interact with each other. MS 70 is hydrophobic (not rabies type) and as a non-polar solvent has certain properties for surface contaminants of like category. Acetone is unusual in that it is partially polar, mainly non-polar and so is a middle of the roader while isopropyl alcohol and other alcohols are more purely polar - as you can see this area rapidly becomes more complicated the more you look at it.

Here is what I do (not saying it is the end all): if there is some crap that looks to be "greasy" like PVC based, I use the acetone with application via clean white cotton towel or pre-daoked Q-tip. I then let it dry & inspect it. If it still has some more crap that may be looking still greasy I then go with MS 70 or equivalent. I then remove the MS70 residual with mild detergent soap and water, and horror of horrors rub the soap into the surface with my fingers (which actually have been degreased by the soap also) and the liberally rinse with water, distilled if you have it and then tamp dry with white cotton towel.

Some of the EAC folks like the residual of MS 70 as a coating on the surface, but I can not speak for all of them. If you do use it, you should still use a part of the towel that does not have acetone or soap on it to tamp off the excess.

What I hate about leaving that stuff (MS70) on there is that if you were to say put the coin into a 2x2 w/ cello you will see the coin parts with extra MS 70 sticking to the cello...Well this is not an end all but just a few more comments.

BTW, the flammable part of acetone is true but if no open flames or cigarettes of any persuasion then should be pretty safe, I keep mine under the sink. The poster above seems to indicate he tried out the xylene for flammability! Wow, that takes some balls....

hiyosilver · July 9, 2007 12:14AM

" common XF coin"

" low MS morgan from 1921"

Anyone else care to guess how it'll slab? It's off to "get 'er done!"

Me thinks it'll AU 53/55......

hiyosilver · July 11, 2007 1:37PM

Anybody else?.....With this being my 1st. acetone bath, it makes me wonder if it'll net grade..

DJCoinz · July 11, 2007 1:47PM

Is it worth the grading fees?

hiyosilver · July 24, 2007 11:51PM

It slabbed AU55..........

WHOOSH!!...no NET.
