Curiosity's killin' me!

When numeys send coins to NCS for "Conservation," what type chemical agents are used to "Conserve" the specimen in order to get it graded and slabbed?image

    I think their methods and the chemicals they use are propriatary. In other works, its secret not unlike the formula for coke.

    This is one of NCS conservation methods.

    You will not get a serious answer because NCS will not disclose their methods. Nothing sinister, just why openly discuss your trade secrets? There are several common methods involving organic solvents and other chemicals. A better question to post is why kind of methods are used for coin conservation (not specifically what NCS does). With that said, do a search through the archives as this has been discussed many times.

    Be careful. If your dog accidentally swallows your coin you may wind up with a coin thats both cleaned and artificially toned.

    Most things are that which you most likely are already aware of or may have heard mentioned at one time or another on these boards. Application ... knowing how to use them properly is key.image

    Don't worry Razor. According to Marty, he really should know if he uses them as much as I believe he does. I mean Marty wouldn't lie. He's not too far off in his answer, actually.image
