Advanced Coin Conservation

Saw a neat demonstration in a private class: 1964 Proof quarter brought back to "gem."

Coin was pre-dipped and than dipped. This left a virgin coin with spots that did not come off after the dip. Next came a two stage proprietary conservation treatment. Spots gone (A few were left untouched for now so you could tell the coin was not switched)! Complete treatment from beginning to end took less than three minutes. Wonder if NCS knows about this one? Class worth every penny! .

Knowledge is power! PS No Hairlines!

Maybe you should share that proprietary process for the cheapskates out there Or is it a secret that only the proprietor knows and charges people like NCS??

 

Was the reflectivity reduced at all?

 

I wonder if it would pass the sniffer?

 

Very nice!!!

 

Ah, better living through chemistry.

 

The proprietary mix was indeed Mountain Dew.

 

No

Don't see why not. Coin was neutralized, dipped in acetone, and air dried. Besides, AFAIK they don't waste time "sniffing" $15 coins!

Used by a technician at one of the conservation services (not NCS).

 

Pretty sure this demonstration on a $15 coin wasn't meant to attract customers with more $15 coins.

 

I would love to figure out the secret formula and procedures they use. They can't keep it secret forever, just ask KFC

 

IMO, that is a very narrow point of view. Business is increased if you do a good job not on a coin's value. I've seen collectors drop off VF common date Morgan dollars to have them slabbed. I hope this post enlightens you:

At the time of the demonstration, the employee was conserving over forty proof quarters dated 1956 to 1964. I have no idea what any of these are "worth." Since I was curious, I looked up a $15 price in trends for a PR-65. What's a PR-67 go for? Besides, if a coin goes from a PR-64 to PR-66 or 67 I'll bet the dealer will be happy and his coins sure will look better and be easier to sell w/o the spots.

Finally, I'm told that conservation is just a process. A $$$$ coin gets the same treatment as a $ coin if the problem is the same on both. Only thing that may change is which member of the team does the conservation.

@Evan8 He used a white gel-like substance.

 

Good point. If the process is easily learned, takes only a few minutes once you've mastered it, and doesn't require super-expensive materials, why not apply it to two-figure coins?

 

Dollar Tree White Petroleum Jelly! Eureka!

 

I was just thinking maybe I dont want to know what they use after all

 

Now, show a little respect for this seminal demonstration of conservation.

 

LOL

 

White gel like substance, Pro sports ban that stuff. Performance enhancing damage?

 

Good Lord.......

 

That's why you hide it just behind the belt

 

Frankly, I find this fascinating. I wonder how much the pricetag will be once they get all the Ts crossed and Is dotted?
