Will a plastic baggie or 2x2 degrade a MS unc coin?

    If so how?
    And also would it go from unc to AU?
    Just curious, I had a customer go on a rant today for 4 hours about this.
    Thanks

    If by "plastic baggie" you mean a ziploc or other bag that you can get at the grocery store - no. Plastics intended for food storage do not contain PVC due to the health hazards. They will not take a coin from UNC to AU either unless there is vigorous and long term shaking. The coins will impart dents and dings to each other if you are not very careful though.

    Not much to add after physics-fan3.14 laid it out all nicely for you.

    The thing in your post that really intrigues me is how anyone could go on a four hour rant, and besides that you must be super patient to put up with anyone having a four hour rant.

    But plastic can mark coins, back in the day when we were kids we used to stay up all night filing pennies into dimes, a plastic baggie can polish up a coin pretty good, so if the coin was loose and moving around in the baggie it could put some lines on the coin.

    Maybe I read it wrong, but one has to consider that the only good characteristic of a PVC containing flip ( there are no PVC cardboard 2x2) over a non-PVC flip is that PVC is much more flexible than say mylar. I have heard a few dealers sell and store their coins in a inexpensive pvc flip as the mylar or hard plastic might leave slide marks which some could mistake for rub and the AU remark. Similar to some of the rub marks that are found from albums that have hard plastic slides. I have seen rub on the high points of some coins that have moved around in a mylar flip.

    Well proves my point.
    Essentially a customer ordered 1200 UNC silver dollars for $27 each. I got him peace, 21, and pre 21's.
    He insisted that if they're in plastic baggie they're no longer UNC. So he would only pay $18.
    Then top that off he decides that he wants an1885 CC AU50 sitting in a 2x2, same argument that the 2x2 lowers the grade so he would pay xf40 money. In the end he ended up taking his order of silver dollars at agreed price according to contract. However he didn't buy the CC. I actually refused to sell it to him in the end, when he wanted it, because it was the stupidest argument ever. Besides people saying the dollar will fail or be worthless.

    Sorry long rant. I just felt the need to be vilified, I was utterly mad with him.

    I think I would have been PO'ed to if I went to pick up a lot of uncirculated silver dollars crammed into plastic baggies. I can see where bullion value can be mistaken for Numismatic value here, the buyer should have been a bit more specific with his order, but the buyer does have a valid point that UNC coins like this should only come from original canvas mint bags, not modern day plastic baggies.

    I would have expected coins to be delivered in coin tubes. Those hard plastic tubes that prevent damage to the coins. (contact marks)

    Happy Collecting

    the coin shops i go to around here, would have kicked him out. i think they have a radar for the ignorants. its funny seeing people trying to low ball like they are at some flee market, but in reality they are at a top end coin shop.

    i bet you are glad you put up with him. at least in the end you got what you were asking. i could see were he would be upset though. were any of them scratched up?

    My opinion is the guy is a jerk. Next, if the coins were/are in a plastic food baggie and they were not bounced around but just put aside, I don't see thge problem of bag marks happening. What I do see is that silver tarnishes and tones faster because of being exposed to air and humidity.
    So I prefer 2x2's stapled tightly so no movement occurs. Make sure to flatten the staples. If you don't you'll suffer damage to other coins and eventually the unflattened staples will break through the Mylar.
    As a lot of you know I preserve my coins, folders, mint sets,etc. by vacuumizing them in food saver polypropylene plastic. This really works well. Here is what I did to 2009 cent boxes. The boxes will recover and be okay too.

    Obviously if someone can rant and rave about that for 4 hours, there is something far more involved in his metal stability than some coins. That is the type of person you should avoid at all costs for your own safety. Such individuals are exceptionally unstable and could actually be dangerous.
    As to any possible damage to a coin in a 2x2, it is possible in some instances. Not necessarily a dropping in grade due to something like wear, but if enough 2x2's are bounced around together, some of the coins will actually get banged and possibly scratched or dented. This possiblilty is worse if the 2x2 is the wrong size for those coins. Example would be a Cent in a Dollar type 2x2. That Cent would slide around as it is handled but it would still take a lot of that to do anything to the coin. Occationally people that staple the 2x2's don't flatten the staples and they could scratch other coins.
    Similarly coins in a plastic bag could bounce all over each other if just loose in a plastic bag. Again, that too depends on the size of the bag, the method used to place the coins in them, the amount of air pushed out, etc.
    Yet regardless of any possible problems with any coins in those containers, the person ranting about that should be hauled off to a place with those people with the white coats.
