Unfortunately I don't know the conservation process. Some more familiar with that procedure have stated it is basically a dip that removes toning.
I'm not a lawyer, but you've stated (in writing) some very libelous accusations.....and in a public forum. Ya gotta be careful of what you say because these guys (NGC) in all likelihood have 'eyes' here and might take exception with what you ve said (written).
The coin type has nothing to do with conservation. NGC grades coins. NCS, Numismatic Conservation Service, conserves coins.
No, pure acetone is fine to do to almost any coin. Ones with a mint applied protective coating, enamelled, or encrusted coins may not be safe to soak in a solvent. I've given a couple presentations about the history of conservation and modern techniques. Probably have a link somewhere if that interests you.
It may just boil down to whether you feel secure in doing a good job cleaning a coin yourself. For instance, take this medal. I got this silver medal in a bulk purchase more than 20 years ago. It looked as though it had spent a long time in a damp basement. I was not certain that I could do a proper job myself. I had never attempted to use acetone before, but I was also interested to see if NCS could do the job for me since I had never used them before. As you can see from the before and after images, even the best professional service cannot claim to fix everything, but I was satisfied with NCS because it now gave me a feel for what can and can't be achieved. Before Conservation After Conservation
NGC charges 4% of the Fair Market Value (FMV)--with a $25 minimum--which is what you stated in the "Declared Value" column on the Submission Form, and note, that if you underestimate the FMV and based upon the grade received it is more valuable, then they will invoice you against you credit card for the difference. If indeed they did conserve your coin then you would see that charge on your Invoice.
Ya see? That's where I got a problem with TPG's........they want to know what I think the value is. What the devil? How in haides do I know? And what the devil has that got to do with slabbing the coin? Oh, heck........that's right........I shoot myself in the foot on so called value of the coin, and you guys charge me more money. Ya want it graded, buy it graded.
Not that I would speak for them but I’m pretty sure they wouldn’t even notice some anonymous guy ranting and raving about a coin they graded and or conserved. How many millions of times has that happen before today on how many different forums. And then good luck proving damages
Quite true, but a warning to those who want to run amok ranting and raving.........you could be held accountable for your actions.
Yes, it's a crap shoot sometimes, but the submitter does have to have some idea of the value based upon what he/she thinks the grade is for the following reasons: (1) your value determines the Tier that the coin will be evaluated in and therefore the per coin charge; (2) for estimating the Insurance that you apply to the shipment to the TPG, and for what they apply to your return shipment; and (3) if you want Conservation, to both determine IF the charge for it will justify the value to you and for you to understand what you will be charged for the process so you will not have "Sticker Shock" after seeing your Invoice. For NGC and PCGS you have to either be a Club Member or for NGC an ANA Member, in order to be able to direct submit coins; I would think that most people that would be interested enough to pay for the ANA dues or NGC or PCGS Club Memberships, would be at least competent in determining a rough grade.
