Today someone suggested that I should check out a product called ms-70 and that it wasn't a cleaner, but it made the devices really pop. He also told me that he has sent coins treated with ms-70 to pcgs and they graded. My question is if it really works, and is "safe" to use on coins.
MS-70 not a cleaner? Hahahahahahahaha. Seriously though, I have heard quite bad results from people using MS-70. Especially for copper.
I have heard others here that like ms-70 but I would not use it myself. I use a product called Verdi-Care that one of our members who is a metals chemist by trade created and sells. However even I would not use ANY product on a proof, MS or uncirculated coin, to do so is a sure way to lower their values.
If it don't come off with Brasso and a Brillo pad, I wouldn't mess with it . . . okay, not funny. Don't clean your coins.
Yes MS70 is most definitely a cleaner, but like all other products it should only be used for specific things because it is only designed to do specific things. Or if you prefer, it only works best on specific things. What MS70 is good at doing is removing light haze from modern Proofs, particularly the clad Proofs. And if it is used properly, yes the TPGs will grade the coins. As stated, unless you like blue or purplish colored coins, do not use it on copper. As a general rule the TPGs will not grade those. Years ago some folks got away with it, but the TPGs caught on and they rarely if ever get away with it anymore.
MS70 is used primarily to remove light haze or surface grime from coins and is a cleaning agent. However, if used properly it will not impart hairlines on coins and the coins will indeed "pop" better, at least in the short term. The TPGs routinely certify coins that have been treated with MS70, but certain coins also are routinely rejected such as over treated copper or circulated coins. In this respect, MS70 is similar to the traditional Jewel Luster dip.
I know what you mean, but just for the sake of those who don't - MS70 contains no acid, Jewel Luster does. And it is quite easy to over-dip and ruin coins with Jewel Luster.
I've use MS70 successfully on some very hazy proof Ikes and some modern foreign proofs and MS coins as well. All the ones that I have submitted to PCGS have passed muster. Just use carefully. I've probably sent in at least ten, none rejected as cleaned or any other problem.
First let me make clear that the specific comments in this post have nothing to do with MS70, but are instead an example of an answer to your question. Say you had a scarce Morgan with heavy, dark toning on it, almost black. In that condition & grade the coin was worth about $20,000. But you, as the owner, decided to take a big gamble. You cracked the coin out and dipped it, you cleaned the coin in other words. As a result of your "cleaning" the heavy, dark toning was removed. You then sent it in for grading and got a 3 point upgrade over what it was previously. The coin was now worth $126,000. That is just one example of why.
i know what we should start. we should start a coin upgradation service. Think about it nothing exists like that anywhere at present. there is conservation and grading but no upgrading service.
Personally, I rather have a black coin than risk destroying it. Coins have survived for so long, over a hundred years or close to it in most cases, and I would be very embarrassed and regretful if I ended up being the end of the line for one. Sent from my SHV-E300K using Tapatalk 4
But do you realize that once toning reaches the black stage that the toning itself can and will destroy the coin ? What I'm telling you is that there are times when dipping a coin is the smart thing to do, what you should do to protect the coin from certain destruction.
