Removing haze from a DMPL morgan

Hey everyone...
Can someone tell me what can be done to remove haze from the fields of a coin? This coin is in a PCGS OGH (if you want to guess the grade, go ahead ) and I'd like to be able to remove the haze from the fields without damaging the coin so I can send it in for a regrade (and hopefully upgrade). Will acetone do this or would I need something else? Thanks very much.

Can't loose by trying acetone. If not, try demel wire brush attachment.

 

I would not try ammonia.

 

What would ammonia do? Have you used it before?

 

I wouldn't touch it. Have it professionally conserved and regraded at the same time if that is the goal. If they clean it, they will grade it. If you clean it, they will body-bag it.

 

I think that one is on Ebay, but to me it looks like it had an acetone bath and was allowed to dry without a distilled water rinse. When they graded that coin it might not have looked like it does now so I would be careful in assuming it looks better after a wash, just my guess on it.

If you want to see what store purchased acetone looks like after it dries take some outside and place it on a very clean mirror. You will see a white haze once it evaporates, and then try to clean that residue. That may be what is on this coin.

 

What he said. :loud:

Well, if it was left from acetone, then acetone should take it off (unless it has reacted witht he silver).

 

Depending on what caused the haze, isopropyl alcohol will work on some coins!

hmmmm, that may very well be what it is. Acetone shouldn't be left to evaporate on a coin as it will leave a film on it. I'll have to see what can be done (after I win it ).

 

Ammonia may hurt the coin as I have learned, and I would recommend steering clear of it.

Just to be sure, what are you calling ammonia? Straight ammonia and water or a soapy solution?

 

Hey zaneman just chose your reply cuz you're a moderator but all of the other suggestions intrigue me.

Why? - because all of these suggest cleaning in my opinion and then submitting the coin to PCGS for reslabbing.
Will it pass or get body bagged? If it risks getting body bagged I'd leave it as it is.

I posted a thread some time ago about a "cleaner" that always passes by the major TPGs. Have no idea what it would do for haze. The responses I got were brutal at times but I can handle that.

Acetone, ammonia? Can't those be just a wee bit harsh?

Would someone please enlighten me on this?

I would not advise using ammonia.

 

I was referring to straight ammonia, however I would no longer recommend it.

 

Acetone and a distilled water rinse should do it.
Acetone won't react with the silver.
VERY CAREFULLY pat dry with a lint-free cotton cloth.
(The "pat dry" part is why many recommend leaving it as is.)

Isopropyl alcohol DOES leave a residue.

Don't know about ammonia, but since it's a base I wouldn't trust it.

 

Blue Ribbon

Hello Zaneman,

The cleaner I referred to was Blue Ribbon. Apparently it's availabe again judgeing from my original post but I doubt it has the same ingredients as they seem to be "environmentally harmful" and not too good for skin exposure.

I originally purchased a bottle on ebay years ago and felt ashamed to tell my local dealers - until I saw it on their shelves.

It is designed to "lift dirt" and leave a protective coating. Works on ALL coins and I have tried it. It will not "clean" a coin hence my wondering if it would do anything for haze.

I have one local dealer that sends a lot of coins in for slabbing by PCGS, NGC and ANACS. He has NEVER had one of the "Blue Ribbon" coins body bagged.

Very easy to use. Put it on and remove with a cotton ball basically.

 

Clembo,
I believe blue ribbon used to contain trichloroethylene, but it is my understanding that the newer bottles do not, as it is now highly regulated. Many many dealers use this as well as coin care, and believe that when the coin gets graded the TPG's they are often aware that the coin has been coated with oil, coin care, or blue ribbon, but they will slab it anyway, as I believe it helps protect the coin from corrosion. I personally don't think it would do anything for haze though.

I will also add that it is typically used on copper, and personally on the copper coins in my collection, I apply a very light coat of extra virgin olive oil, since I know it doesn't contain any other chemicals.

 

I think you have nailed it zaneman. I have used it on all types of coins as mentioned earlier. It removes dirt and adds a protective coating. Preserves the color on copper very well.

It won't remove verdigris etc. It will clean dirt off of the verdigris if that makes any sense. More of a preservative than a cleaner that's why I question what it might do for haze.

I, personally, have no real desire to "clean" my coins. Original dirt is usually good dirt.
