    So I have been taking a look at a lot of ebay listings of many 2020/21 sets AND in local shops, and more than not the coins in these past two years have this hazy issue. I really am starting to think something is wrong at the mint. Very sad If you ask me. 2019 and before usually seem fine.

    Well, when you consider that the haze issue has existed for over 70 years, all in spite of more changes made by the mint in literally everything more times than you can count, and still the haze issue persists - the mint being the problem kinda seems highly questionable.

    As long as air can get to coins, toning on coins is inevitable, and haze is nothing more than toning.

    I just mean it’s clear they have changed something about the fabrication of these sets in the past two years. I picked up a new set from my dealer with the same issue on different coins, nearly all of these sets have the same issue. I plan to mix them to make the best complete set I can.

    I just want one 2020/21 set that doesn't look like this fresh from the mint! Lol

    How does this come out from the mint looking like this and deemed acceptable was the original point of the thread. Not particularly hazing over time.

    That's expected, you know. I give them a break after being over 10+ years old - Just these are new products they shouldn't look like that from the get go. Oddly enough since I now have two 2020 sets I opened the worse off one and (please forgive me) I was able to wipe the haze off with a plastic glove. Did this out if pure curiosity. Put said coin in a flip and I will have to see if it comes back.

    I have no doubt that they have. I say that because the mint is constantly changing things. And no matter what changes they make or have made over the years and decades, the coins toning has never stopped. And it never will stop, no matter what they change. That's because what the mint does, does not cause the toning !

    It's deemed acceptable because toning is the nature of coins. All coins begin to tone the instant after they are struck. People seem to think that toning takes years to occur, but that simply is not true. Toning begins immediately.

    Hopefully you're aware that you caused permanent damage to the coin by doing that. But, if you bought some MS70, opened the sets, held the coin by the edges, and quickly dipped the coin in and out, then rinsed in distilled water, the toning would have disappeared like magic - with no harm done to the coin !

    I am. The coin was already screwed in the first place.

    I think you are misunderstanding. THIS (in the photo) is NOT acceptable for a brand new proof coin. That's not normal. If it was, ALL proof coins would look like this after a week, and be beautifully toned within a year. This coin has become my experiment, I do not care about it since I can easily get a 2021 proof dime in a slab that's graded and mostly airtight. I think more is going on here than toning, I did not expect to be able to wipe it off with one swipe of the glove. It seems like some residue of some kind I am very curious to see how long it will take and if it does come back. My other 2021 proof dime is fine. In the before photo these all look like butt if you as me. :)

    takes years to develop usually, but begins and occurs immediately, you ain't wrong!

    Can haze be wiped off like that anyway. I really didn’t expect that. Next time
    take a look at my 2007 set. Now this is toning I can appreciate! And being 14 years old doesn’t bother me.

    Yeah, early enough sometimes it like a mist on a mirror. sometimes it's solid but still you could rub it off with enough contact. You shouldn't really wipe or touch proof coins in my personal opinion, but they are yours and you're free to do what you like with them right? :)

    it's all gotta start somewhere is all I'm saying, once it's started, trying to stop it from continuing in my opinion just leads to the same hazy coin a decade or two or three later without much change.

    possible the haze was a oil solution from the strike or something on the coin surface. hard to really say.

    I'm a fan of that 2007, and probably will be a bigger fan in another couple decades. hahaha

    grease makes sense. I think if it was haze alone it would be on both sides of the coin. But usually only one in these examples.

    If it comes back in a few years I think I can live with that anyway. it will no doubt look different. This tallgrass prairie example I shown is absolutely not just haze, it’s smudged like whoever put it in wasn’t wearing gloves.

    Kinda sorta, but not because it's a film or foreign substance of some kind. For lack of a better way of saying it, what you actually doing is mashing down the very top ridges of the luster flowlines thus rendering the early toning invisible.

    Ya see, when viewed at high magnification luster looks kinda like this - /\/\/\/\/\/\ And the very top of those ridges, well it's like a single molecule of metal, and it's very fragile sitting up there all by itself. And it is that single molecule that has toned, corroded in other words, purely because it's more exposed to the air than any other metal on the coin. And when you wipe it like you described, what you're doing is mashing the very tops of those ridges down into the valleys between the ridges. And rendering them invisible because they can no longer reflect and refract light that strikes them. So you're not wiping it off, you're just mashing it down.

    I forgot to mention this.

    Actually the coin wasn't screwed at all. Ya see, the haze could have been rinsed away in less than 2 seconds. Poof ! - it would be completely gone. And, the coin would not be harmed in any way shape or form. And it would look exactly like you wanted it to look.

    I understand where you’re coming from but it is my coin. However next time I will use MS70 or some kind of dip. I would still consider it harmed even then. I called it screwed because it’s either that or leave it as it is. I don’t particularly want a coin like this. It’s just my experiment now, I hopefully can learn from. :)
