- In this episode, Junior and I clean 2 silver coins. One has already been improperly cleaned, and the other has PVC damage. let's see if we can either restore these coins, or stop the damage in its tracks.
Great to hear Junior's interest. Thanks
Thanks for the video, I think I'll pick up some MS70 to try it out! Here's my process for a PVC damaged silver coin: 1) Ultrasonic acetone bath to pull soluble plastic and oils. 2) Ultrasonic soapy water to pull water soluble dust and acetone residue. 3) If there's bad eye appeal I might in rare cases dip. Don't tell anyone! I'm considering MS70 as a possible replacement or compliment in some cases, but the need for physical abrasion would limit my use. 4) When the coin is looking as good as it will get, it's off for a tap water rinse, followed by a tablespoon of distilled water since my tap water is high mineral.
Heck, any time I get new coins, I do steps 1, 2 and 4 when they arrive. When dried well, i put them into paper flips and for a few years to maybe pick up a bit of attractive tone. When a coin looks perfect I put it into a Kointain to freeze them in time.
I love MS-70! I use it mainly for cleaning my 40% half dollars and I have seen from remarkable changes to some half’s that were very dirty! I also clean the reeded edges and the whole bag looks unbelievable! Great how to video!
Does it actually work?
Love the informative video!
Actually a cheaper option to remove milky film due to PVC damage is to use a sudsy Ammonia based cleaner (with no bleach or acidic). Best way I have found is to soak the coins in warm water and with a few sprays of the ammonia based cleaner for a few minutes. Then in a paper towel soaked with the cleaner have the coin wrapped around. It should remove the the milky film and look fresh. If there remains still some film, spray directly on the coin and with a Q-tip or paper towel lightly pat the coin. Rinse. The result you got with the WLB is similar to what I got when I applied to some 1969 Mint sets. There still were a few coins that remained irreparably damaged - noticeably the cents as copper is more reactive than silver and nickel.
Awesome feedback, thanks for those tips!!
You should never rub a coin with a qtip.
Pull the cotton loose and roll it over the surface. If that were a Morgan Dollar it would be ruined. Covered with hairlines.
@@bl7121 Technically you should never rub a coin with anything as it will produce hairlines. I edited my comment in light of your astute comment that the Q-tip method is only a last resort. Note too that I wrote was PAT a Q-tip to the surface (or a paper towel) not rub.
My commemt was based more on the video than your comment. Just to be clear.
I know it's very tempting to really dig in but the surface of an uncirculated coin is very very delicate. I'm sure many experienced collectors are aware of these things already but novice collectors have no idea. Been there done that.
Acetone works to remove PVC and tape residue in a non-distructive way.
Enjoyable and educational video! It looks to me like you improved those damaged coins quite a bit! I was a little puzzled and amused about the product, however. "MS 70" is a great name for marketing the product! They say it's safe to use on a variety of metals, including gold. It probably wouldn't hurt a gold coin, but I don't know when or why anyone would ever need to use this product on gold! Your advice is very good and sound, and should be well taken: don't clean your valuable numismatic coins! There's a broken heart in every jar of E-Z-est; some are yet to be realized. Best of luck to you and your young assistant! Keep up the good work!
Chemical sniffers? That’s interesting and you’re the first to mention what I’ve wondered about coins that were identified by graders as cleaned that weren’t obviously visibly cleaned. How do they know that, I wondered, unless they suspected a cleaned coin but verified it by a chemical detecting agent/process. If so, do graders have an acceptable range of cleaning, i.e, percentage of cleaning solution detected? Some dealers admit having submitted cleaned coins but they were slabbed and other coins received detail grade “cleaned”.
Thank you sir
Dip it in The Crown Royal. You never know.
I dip coins all the time for years! 2 sec dip and rinse. Wear rubber gloves then final dip into distilled water. Hair dryer to dry each coin. I grade them and they have all graded straight! The longer you leave the chemical on it will compromise the original surfaces which you can get a cleaned, or details coin.
Having seen the ugliest, spot-filled 1916 D Mercury Dime that was full bands PCGS MS 67 I am leery or cleaning anything that isn’t obviously already harmed. That dime needed dipped but I wouldn’t chance loosing tens of thousands of its quarter million value. PCGS does offer restoration but I don’t think I’d take a chance. I’ve seen some dipped and graded and came back great. I’ve seen some graded as cleaned. As you said, you better know what you’re doing. Put the baking soda away.
What is your preferred coin cleaning product E-Zest, MS 70 or other?
Would this stuff clean a 300 year old coin just curious
Olá boa noite , como tirar risco das moedas ? E se tira perde o valor ?
I have several silver Eisenhower Dollar coins. previous owners removed old tape from the faces.. what should I do?
If they have tape, I think the best course of action might be acetone. They are only going to be worth silver value with a big tape "goo" on them - so give it a try. However, use 100% acetone, not the 90% nail polish remover.
@@numismaticsanonymous4952 thank you!
I assume pure cotton tipped applicators should be used. Some so called cotton tipped applicators are actually made with a synthetic material.
the question is, where do we get pure cotton tipped swabs?
Is it ok to rinse the coin with mineral water or seltzer?
I would not try that.
Im no expert at all. But I cleaned a type 2 1979 Kennedy and it became tarnished looking. Looks like some kind of silver paint rubbed off. 18 dollar proof Kennedy so wth. Definitely impaired. But never seen one go from a milk spot to completely tarnished. Lol. And that’s after cleaning. Huh???? But I’m with you don’t clean. Only with cheap and ugly coins. Maybe melt value coins which I’ve cleaned plenty off. And toned. I toned all my beat up $4 and $5 jfk p and d 65-69 just to make them look better. Lol.
I've had several Pieces of silver come out of either the ammonia bath or the baking soda, water and foil bath with mega tarnish on them from the bath. It's weird. The dip sometimes makes silver haze and whitish.
It'll turn your copper Pink, looking
Have you ever seen anyone use a laser to clean coins? I have seen laser cleaning videos maybe check it out?
I use sand paper before i sell mine for top dollar
Don't clean silver coins at all...WTF people!!!
Instead of repeating over and over "do not clean your coins" why don't you make a useful video where you show people the proper way to clean coins. Once the coin is already damaged what's the point of cleaning it.
Thank you so much for watching and leaving a comment. I believe I very clearly stated that if someone doesn't know exactly what they are doing, please do not clean their coins.
Most people, even with good advice, will harshly clean coins and think they are doing good, but have done irreversible damage. The disclaimer is more helpful than an extensive how-to.
@@numismaticsanonymous4952 would you recommend practicing on cheap PVC damaged coins? Like anything else practice must make someone better I'm guessing. My father left me a bunch of old peace dollars and Morgan's. I sold a lot of the common dates as is and am left with a good chunk of key dates. Alot of them have beautiful details but unfortunately he had them in the cheap PVC holders. I would never start out with any of them obviously but would like to practice on common cheap coins and if that goes well maybe I'd consider taking a whack at one of those. If they were PVC residue free I could see them getting mid ms grades give or take on some
Annoying
