This sm dt is a $40 coin in pristine condition and hard to sell with a haze.
In '75 the '60 sm dt was worth more than the '70. Now few people realize just how few nice '70 sm dt's are still around. Most come from the mint sets but the mint set coins are tarnished.
Most of these coins look far worse in hand. Clads tend to turn very dark if left long enough.

I have a few sets that have that "hazed" tarnish. After coming across this thread I went through them, picked the 2 most affected sets and put them aside. One is an '84 and the other, if I remember correctly, an '80. These were the worst of them. I'm gonna dig into them this weekend when I have time and post some pics!
The '80 set tends to be either pristine or terrible. It is one of the toughest to clean.
The '84 isn't too bad but a few are. The '84-P cent is ugly and the '84-D has lots of carbon spots but the clad is usually still OK.
Sometimes you have to cut them loose to see what's hiding under that dingy plastic. One example I just cut loose:

But then again, you have to have a strong stomach when you find out that 64 Proof Set you have been sitting on for fifty years, has Damage from the plastic on a DCAM Kennedy Half Dollar.

You have to look close around the L and T in Liberty, the coin has been etched by the plastic. 😡
The only thing that would be worse is if it had been an Accented Hair Variety. 🥴

You have no idea how long I've waited for an excuse to crack these all open. Thank you so much for the information.
What do people put their coins in these days? I've never found a perfect medium between staples and flips. I have some nice raw coins and don't want any compromised.
and are nitrile gloves okay as a temporary substitute for cotton?

I am not sure the plastic ever touched those spots. They are protected by high points around them. The plastic would have beent touching the high relief areas and the wide open fields.

Most of the coins I've put in 2 x 2 cardboard holders over the years are fine. All of the ones I put in after soaking in alcohol appear to be OK but this is a small sample size. Coins in tubes are usually OK if stored in a decent environment. Even tubes in bad environments tend to be OK. High quality flips might be OK but I've had bad luck with even some expensive ones.
Now days there are a few very expensive media and these are probably OK.
Bad sets are going to be on the market forever. And as time goes by the percentage of bad sets will probably increase even if collectors start taking care of these coins. But if the situation becomes more generally known and steps are taken to save these coins it will have two effects. First and most critically it will preserve coins for the future. Second and also critical, it will create a two tier market for mint sets; tarnished and pristine.
This will result in the scarcity of many of these coins being seen now which will aid further in getting more coins protected before it's too late. It will also reward the few who had good storage rather than raw coins in safety deposit boxes.
I know cutting these up offends a lot of collectors which is why it has been so profitable over the years to cut them up and sell the pieces. I know a lot of collectors expect large premiums to develop on intact sets. I know collecting intact sets is a lot of fun and I've always saved the best I could find, myself. But I also know that the any premium on these sets will be based on the aggregate value of the coins in that specific set. If every coin in a set was mediocre (about 40% of sets have only mediocre coins) and then every coin is tarnished then there simply never will be much of a set premium FOR THAT SET.
I thought the post 1963 US mint sets were package in inert Mylar.
The outside of the packaging appears to be mylar.
The inside is a very soft and very thin layer that is apparently reacting with the coins or is causing something else to react with the coins.
Later date mint sets (post-1984) apparently do not have this and are solid mylar. However a few coins in later date sets are darkening as well. The causes of this are not clear but to my knowledge once the coins are stabilized they are OK. While few later clads are affected they seem to be even harder to restore and a lower percentage can be restored.
It is very curious that the '72 set is mostly unaffected.

Maybe this is all a scheme to increase the value of mint sets in original packaging.
After all, without the packaging aren't most mint sets just a pile of well-preserved pocket change?
Anything that draws attention to moderns is potentially very important as far as price is concerned. These coins have been around half a century and people just don't much collect them because they are all considered "common junk". Everyone "knows" there are millions of them so interest is very low.
The reality is many of these were actually scarce or uncommon and now that many of the raw moderns (mint sets coins) are damaged it will become apparent to more and more people that they are so tough.
Think of it this way; a lot of collectors have a few 1970 mint sets sitting around because they like some of the coins in them. They actually like the coins. If they find their sets damaged and some of the coins can't be restored they might go out to try to replace them. And then they'll find replacing them isn't so easy as they think. '70-D nickels aren't even worth 6c each because so many are ugly and there is no demand. It used to be easy to find nice gemmy coins in mint sets but not so much any longer since this door has been closing so gradually it was never even noticed.
If people don't start acting to preserve these coins then they will be lost forever.
Every indication is that this is a growing problem. Early clad is self destructing. I used to kid people that the "Explosion Bonded" clad would one day explosively fail when the warranty expired. The many layers of mint set plastic are destroying these coins just as surely, though.

I'm afraid this is very typical for this coin. It has a heavy haze that usually can not be removed and it is covered in carbon spots.

This tarnish doesn't look as bad in photos but it really is ugly and it is pervasive.

The '72 set is usually OK and the '73 is almost as good.
The problem starts back up with the '74 and continues through '81.

Aren't they that, even with the packaging?
