A couple of things - unless you know for a fact that the coins to which you refer were in your father's collection from the time they left the mint - you don;t know if they were cleaned before he got them. So, it's possible that they had been harshly cleaned. Harshly cleaning coins has been going on for centuries. The other thing is this - there have been more than few examples of coins submitted to PCGS straight out of Mint Sets that PCGS sent back as having been harshly cleaned. So it is also possible that the coins you refer to were not harshly cleaned at all. But it is very important that people realize that just because a coin or group of coins have been in their family for 50 or a 100 years - and nobody in their family would ever harshly clean coins - they have no idea what was done to those coins by the previous owners. Especially since harsh cleaning was THE thing to do to your coins for hundreds of years. Now - in repsonse to your previous comments back to me. The reason for my comments to you about the coin you worked on is this - a problem coin is still a problem coin no matter what you do to it. Problem coins cannot be fixed, repaired or made better - by anything. It is important to understand however that not everything makes a coin a problem coin. Dark or ugly toning for example - that can be fixed by dipping the coin. Light verdigris - that can be fixed as long as the verdigris is light enough and has not corroded the coin. Those are just a couple of examples. But a coin that has been polished, harshly cleaned, whizzed, over dipped, altered, damaged, etc etc etc - those things can never be fixed. Once a problem coin - always a problem coin.
****Not to change Subject**** Pcgs is saying the will help tell if your coin has been dip or anything like that.plus it will help to find it if it get stolen.
But only if the coin has already been graded under the Secure Plus system. It other words - it can only be detected the second time around. Because only those coins graded under the Secure Plus system are even in the database.
I agree! but they also claim a new raw coin that been Doctored/Dipped or mess with that box will tell them???that what ad claim's Pcgs already has a case pend on a few dealer the claim have been Doctoring or they think they now it up in court.but time will tell as all the new toys come out to save them for the 3rd party folk's
The whole concept is reminiscent of Depression Era Medicine Shows and Hawking Tactics . Keep a short and solid pocket fob !
Which dipping product do you recommend for copper coins? The returned PCGS coins came from a roll from his birth year set. From what I understand, during his college years at Vanderbilt in the late 50's he wrapped them in a tissue and then a steel strong window wrapper - They look machine wrapped, however from my understanding the steel strong window wrapper was for DIYer's. So you're are right, I really don't know.
I'd agree with this statement if referencing covering up problem coins. However, I think it has a place in assuring proper "natural" toning on no problem coins.
You're reading more into that that is really there for that is not what the ad says. It says quite clearly - any "previously registered coin". Send in a raw coin, or even a coin in an older PCGS slab - and that machine will tell you exactly nothing.
There is no dipping product I recommend for copper. Dipped copper is easily detected and rarely does it turn out as well as any of the other coinage metals.
That, again with all due respect, is an unproven assumption. Actually, it depends on the preexisting conditions as well. And as with all complex, multivariable equations, the long term results are highly dependant on initial conditions. Initial conditions modified by your product. So while the underlying chemistry is a fact, you cannot deny that the results after thirty years are both highly dependent on initial conditions and not predictable in the least, and your assertions are based on assumptions not experience.
Another assumption without basis in experiment and long term observation. The natural process occurs via gasses. Your process uses (presumably) a liquid. How you can argue they are similar in the short term, much less the long term, is completely beyond me, and I am hardly ignorant of chemistry or physics. Sure they both use H2S, but they apply it at different rates and through different methods. In addition, there are other oxidations that occur on the surface of naturally toned coins (chlorides, for example, rather than sulfides), that say to me the results, particularly after time, will be different.
I believe Thad addressed chlorides earlier, noting they affect the coin as soon as minted and his H2S process is a gas, not a liquid. Granted every coin will be exposed to a different set of elements over 30 years, so it would be impossible to exactly determine how a particular coin will look. But, the H2S gas should have the same affect as if exposed naturally. The coin should look great after 30 years if toned as desired and then properly sealed in an Air-Tite, much better than one left to chance. Like was mentioned earlier, if AT is done properly, it’s impossible to detect, so, how can there be a rule/law that prohibits that which cannot be detected? I’d also speculate that if artificial exposure to natural elements, in order to produce a near perfect aging of a coin and then encapsulation, is accepted, it could be construed as conservation. Might as well sit back and enjoy some awesome looking coins that appear/are natural. I understand the concerns of those who have invested in naturally toned coins, But, advances in technology, while undermining values, give the consumer a better deal.
pcgs - poor coin grading service ngc- nincompoops grading coins they are okay at best for us coins for other coins run as far as your legs can carry you
hear the audience thad start making something to bring back the luster on the coins. thats a challenge even for a genius. i recommend ncs they will fix it for you the right way so they are a product well in our olde days we had the oracle at delphi if i recall correctly you were always too shy to visit otherwise we would have got all our answers there plus you were younger then or shall is ay less older so your charms may have worked what about ncs no no you will destroy out next gen of products we need to make some products that will solve all of what gd is saying
What about them ? Nobody even knows what methods NCS uses. We only assume that they dip coins, but we don't know that they do. Nor do we know what it is that they might dip them in.
