Do you think I should submit my NCS "conserved" coins for Secure Plus grading?

I mean, just going from that coin sniffer video, that dog sounds like it really bites. Do you think if I tell them in advance these are NCS "conserved" coins, and not "doctored" coins, they'll keep that dog on a leash?

Seriously, would you ever send one of these coins in to Secure Plus? That's really all I'm asking...

It depends on what they did to conserve the coin. Does NGC place ALL conserved coins in NCS holders? If NGC doesn't place them in NGC holders, I'd think PCGS wouldn't place them in PCGS holders either?

Broadstruck · February 25, 2011 2:36AM

No since there's no way of knowing what chemical NCS used to conserve it.

Some make it into NGC holders and some don't. I had a few conserved about 5 years ago that made it into NGC holders and later crossed into PCGS holders.

NGC doesn't have a security dog.

Got a picture or two of the coins?

A truffle sniffing pig?

That's what I'm thinking, Broadstruck.

And, remember, folks, the question is on the Secure Plus tier, the tier with the dog...

HAHAHA LMAO!!

My take of PCGS`s video of the sniffer was that even if the alert (bark) sounds the coin would then be reviewed...My speculation would be that so long as it`s surfaces aren`t damaged and the quality is all there it would be a go...But that`s at best just a guess and my take of it...

NCS are professionals and you can be sure all chemicals that they use are rinsed/removed from the surfaces of the coin. Sometimes removing ugly toning exposes an old cleaning and these coins wouldn't grade. Detailed pics would help.

scottgardener · February 25, 2011 3:58AM

The sniffer detects and identifies substances. If the substances identified are things like acetone and dipping agents that, while controversial, do have some use that at least some professionals consider legitimate, then the coins stand a good chance of crossing. The sniffer does not automatically cause a coin to reject, though it's finding, say, pee and wood putty, would certainly cause the graders to reject it. NCS I would think stays away from such materials, since they are more about removing PVC residue, actively eroding tarnish, and so forth, though I understand that they do dip. (As long as they don't inhale...)

I cracked an MS64 1939 s walker contaminated with PVC out of a first gen PCGS holder and sent it to NGC for conservation.... they cleaned it up and then proceeded to holder it as a 66 coin. I then cracked it and sent to PCGS, they concurred via a 66 PCGS holder!

That was before the big sniffer dog was born!!

PonyExpress8 · February 25, 2011 5:37AM

NCS provides a reasonable service and they take care in what they do. If you think the coin might grade then give it a shot. I have had success in the past.

Teva · February 25, 2011 6:22AM

I would say not as a rule but you should try and let us know!
I was told by one of NGC member dealers that NCS did not use any chemicals and that there methods involved using compressed air
to remove contaminants and organic material from the surface
of a coin?I always questioned that statement due to the color changes I have seen on some of there conserved coins.
Was I sold a bill of goods or have they changed there policy's
and methods???

Oh, those coins have graded, there's no question about it. But, then, there was no Secure Plus dog around at that time to give them a big bite in the ass.

Teva - Still debating over whether I want to be the guinea pig on this one, so, stay tuned on that. On NCS's use of chemicals, though, ever seen their "Coin[s] of the Month?" I think that's what those were called. They used more than compressed air on those, let me tell you.

PCGS would have removed it for you...

IrishMikey · February 25, 2011 7:02AM

I would, but then I am a born troublemaker.

However, even if a "conserved" coin found its way into a Secure Plus holder, what would it prove?
If the conserving was properly done and left no residue, it should not be kicked out by the new
technology.

Are you kidding? Destructive analysis works very simply to provide the answers on this. Send a few cheap coins in to NCS, knowing the problems, and test them afterwards.

Some of what they did sucked, but it's old news. A few of their curation/conservation processes were discussed and detailed with web links to a paper from some chemist at U of Pittsburgh. Dr. Donald Knaack, research chemist for DuPont and coin devotee, has been contributing and advising others for years and years.

On another and more important point. PCGS has an absolute right to sniff anything and reject anything for whatever reason they might choose. It would defeat the idea of the sniffer to reveal what it was programmed to detect. And my guess is that, over time, it will get smarter.

kurtdog · February 26, 2011 2:25AM

Yeah, I think you guys talked me out of it. It'd be like teasing a rabid dog.
