I see in my collecting life many collectors who claim that they can clean without make any harm.But they just polish the coins and pull out all the surface.On these coins, ''cleaning'' in your terms, I think was a reveal of the beauty of the coins.In every sector of our life you can find professionals and amateurs.May this thing not differ in coins.That's why we tell the newcomers that cleaning can harm the coin.

Yes epop, your coins came out very beautiful indeed. I just wonder 'how did they do it'?

Evidently all CONSIDERED Can you promise you can do the same without hearting the coin?

I am totally ignorant of all of this epop, that is why I am asking.
Will heat produce the effects displayed on your slabbed coin?

Quote: Will heat produce the effects displayed on your slabbed coin? Chemical processes in which heat plays a role. NCS does nothing physical to any coin; it's all "touchless," at least in any sense which is detectable in the future. I've taken a rose thorn to coin crud and left no visible evidence..... I do not know precisely what NCS does to a given coin. The process must differ depending on the coin's composition and challenges. But, certain metallurgical and chemical truths do not change, may be studied in a scientifically-rigorous approach and alleviated using known processes. Again, it's not cleaning only because they do it.

Yes, I was thinking maybe something in the way of electrolysis. Interesting about the rose thorn.....I could see that working better than a dental pick or a toothpick, but what I thought what I was seeing on the coin in this post was a return of original finish. Maybe I was just imagining that though.
edited for grammar.

Rose thorns are cool - enormously sharp and strong, yet softer than coin metal. Of course, I used to grow roses so they were always a handy tool.
Tarnishing is a chemical process. Easier to undo with silver than copper or bronze, but not impossible in any event.

Did you say what it eventually cost for that service? Was it compatable with most TPGs?

Suitability evaluation is 1% of the declared value of the coin (understanding that this must be a realistic figure), and conservation costs 4% of the same. If you choose to then have the coin submitted to NGC for slabbing, normal fees apply whether the grade is Details or not. If I've come across as sarcastic, it is with the understanding that I freely admit these guys are good. They can perform what you and I would consider miracles.

Not at all, I was just to lazy to do my own research. Well that, and I probably, maybe, sort of have one or two I would send, but really think it's not worth the cost.

NCS website.And in case it hasn't been made clear from the previous posts, NCS is owned by the Certified Collectibles Group, which also owns the NGC slabbing company. NGC have a vested interest in making sure NCS-conserved coins get slabbed without being branded as "cleaned", which the other TPGs do not have.
