    I recently got a bottle of ms70, and did some experimental coins. I did a 1941 wheat penny in RD BN condition, and just did a test. Well, the results were better than expected - the ms70 took off all the brown and revealed some beautiful toning underneath. I'd say this coin is in AU55. But it looks very cool after the ms70. Here's some pictures: download_20200512_093540.jpeg download_20200512_093547.jpeg

    I've also found that ms70 works on silver too. Any clouds of black/brown on silver and usually ms70 will take it off. Did any of you know about this? Before I used it, I had never heard of this before.

    No. I have read mixed reviews over the years.

    I side with those who say, "No doctoring of coins,whatsoever." :)

    I'm assuming you simply let the coin sit in a small amount of MS70, similar to an acetone bath?

    I applied it with a Q-tip, as instructed on the bottle.

    I assume then that it is highly probable that people are using this substance on old circulated coins and passing them off as higher grades than they should be!

    Just another way to clean a coin.

    IF it is for your OWN use and you do not plan to sell it so ANYONE without the disclaimer "CLEANED" attached to the coins fine. Please do not offer something up for sale that you know is not what it appears to be. It is FRAUD. If you think that the coin cannot be detected as cleaned, send it to NGC/PCGS and watch the reply.
    The art of coin collecting is to find something that is truly unique but ORIGINAL.

    How many cleaned coins would you reckon are in NGC and PCGS holders?

    The duped ones will be those that buy these super nice looking coins with no knowledge that they were ever cleaned. Just another ebay fraud. In action. A lot of that going on, some known cases, some unknown.

    "Contains no acid", but it does contain a very strong alkali - sodium hydroxide (caustic soda). Seems to me that it would tend to ruin the coin if not done right, and even then cause some damage to the patina and finish.

    Welcome to CT. You are probably correct. I say probably because there are those who would argue the point.

    The MS didn't "reveal" that toning, the MS created, caused that toning ! MS70 is very well known for turning copper coins blue and or purple. You should never, ever, use MS70 on copper !

    I would guess a minimum of 60-70%.

    Better make that 80% plus ! For older coins anyway. But it needs to be noted they were not harshly cleaned, but properly cleaned.

    That said, they also have a way more than their share of harshly cleaned coins, cleanly graded and in their slabs.

    Ahhh! "Properly cleaned." The operative words. They should include those words on the slab, don't you think? :)
