Well, I can certainly see the Tao aspect in this - cleaning/dipping to make it look nicer but quite possbily losing some of its value........or not cleaning it, retaining its value and looking at an ugly coin.

Those who are into numismatics will tell you not to clean it.

Those not, will tell you clean it and screw the numismatic aspects.

Having said that - its up to YOU to decide which side of the fence you are on.

Personally, as one of the first group, I would not clean it - and certainly not clean it myself - I would take it to my coin dealers - discuss it with them and if they thought they could dip it and not have it lose its value (they do that a lot) - then I would let them IF they felt it would not hurt its value. (I already have one Morgan that is worth only is silver value due to someone cleaning it so poorly PCGS wouldn't grade it - I didn't pay anything for the coin so I lost nothing - but it could have been worth a lot of FRNs!)

But - finally - many, myself included, and authors of leading numismatic books, think shiny older coins look fake...........

I know - this was no help! :D

Use Brasso and some Comet or Ajax. That will take that unsightly green right off.:sarcasm:

DO NOT clean it. It's worth more green, than clean.

you spent a lot of money for less than an ounce of silver...dont destroy its value by cleaning it. keep it as is.

It's an (eh hem) eco-friendly coin.

Re: Numismatic question - all input accepted
 

Re: Numismatic question - all input accepted
 

Respectfully - is that really the right question?

If you go to sell it and expect anything like its value - who will you sell it to? (ME! ME! :D)

Someone who wants it for its numismatic value.

Will it have the same - or any - numismatic value if it looks better but is cleaned?

I believe acetone is what they use, but don't take my word. The guys over at the PCGS collectors universe forum can help you.

Type in acetone

Yess - I think you got a GREAT deal - and no, I, personally, sure wouldn't take a chance of losing a dime of its value by cleaning/dipping it! I don't think its wussy at all!

You might look into the restoration services the grading companies offer. That PVC stuff is notorious for killing coins. I forget what it's called but with copper coins, if you don't remove it, it will eat the whole damn thing. These are 10% copper so you might do some research.

Trichlorotriflouroethane Neutral Coin Solvent (available from E & T Kointainer Co., Box 103, Sidney, Ohio, 45365).

This solvent will NOT remove anything but grime, grit, and polyvinyl chloride, the green gummy stuff that migrates onto the coins surface from being stored in vinyl "flip" coin holders using PVC based plastics. The problem is that some coins with this green goo have been exposed to it for long periods of time, and it has caused some slight corrosion to the surface of the coin. Once removed, the corrosion is apparent. The solvent itself will not damage the surface of the coin like regular coin "dips" will. If the coin was "toned" or tarnished before the PVC goo started building up on the coin, so much the better, as the actual toning or oxidized metal helps protect the original surface below.

Avoid regular "coin dip", as it usually does more harm than good.

Isn't that the stuff they used to use in fire extinguishers?

Not sure if it was or not. I do know that it is extremely volitile, evaporates almost instantly, and leaves the coins cold to the touch....... almost like spraying them with freon.

Re: Numismatic question - all input accepted
 

I'd be careful. As for wanting it to look "pretty," couldn't you have gotten a common date Peace Dollar in MS63-64 for about $35-$50? So you paid $300 for a numismatic rarity, the last thing you want to do is destroy the numismatic premium you paid.

Re: Numismatic question - all input accepted
 

Found it. Tetrachloroethane is the stuff I was remembering.

I found one thread at cointalk discussing this: http://www.cointalk.org/showthread.php?t=11813

The green stuff is called verdigris and you should look into it.

Re: Numismatic question - all input accepted
 

The term "verdigris" is more commonly used to describe the green copper oxide corrosion found on copper or brass coins. This green PVC migration is a completely different problem.

Re: Numismatic question - all input accepted
 

Not Verdigris....It's called toe jam.....
really.....if you paid $300 for a graded coin it should be slabbed, right...and you are asking if you should un-slab the thing to clean it???
C'mon.....
Just save yourself the trouble in the future and buy $300 worth of gold bullion...
my 2 cents...

I think the poor detail on GW is an inherent part of the design.

Also, weak strikes are generally not collectible errors, just "sucky" errors-- from what I can tell.

Scott Travers makes a lot of fuss out of the fact that the major grading services will rate poor and good strikes alike, except for ms-70 of course, in which a perfect strike is a requirement-- but in other grades strike is not rated. That is what part of this CAC sticker thingee is about I gather

Re: Numismatic question - all input accepted
 

soaking it overnight in acetone or using the trichloro will not hurt the surface as long as you do not scrub. Rinse with water and pat dry with soft towels.

do not scrub. :D

do you have any pix of the coin, Great Ag?

Re: Numismatic question - all input accepted
 

I had some Barber dimes stored in a popular brand album that turned out to be full of PVC/ The green slime was on everything. I swirled them one by one in a glass of acetone and it removed the green nicely. Lucky these were circulated coins so it didn't make much difference.

Re: Numismatic question - all input accepted
 

Send it to ANACS to have it graded. They grade problem coins.

Be careful with the acetone. It will ruin the finish on a wooden table. I keep some out in the garage and don't bring it inside.

Re: Numismatic question - all input accepted
 

what brand was that, & was it an old one or a new one?
