I have searched through a lot of new 2018 and 2019 rolls of quarters.

I have noticed some have a matte haze finish and some are super shiny almost mirror like. Why is there such a big difference in the same coins? Is one from a fresh set of dies versus a worn set of dies? I have read for an example that proof dies would lose their cameo finish after they were used quite a bit and turn mirror like, is this sorta the same what I am seeing in these quarters or something else ?

Not sure what you mean, do you have an example picture possibly? I know Lowell P for instance on the obverse had this hazy ring to it, sometimes even partially ringed, on a good amount of the quarters I searched, while others were free from from it completely, I had thought it was due to slightly overgreasing the dies.

Also seems like NGC is grading some State Quarters as "PL" which I would assume is proof like.

I know occasionally there are just better coins struck than others and also as dies wear they get worse until the dies are retired. and Denver seems to have better strikes than Philly, just various things going on in the minting process. their goal isn't perfect coins, just acceptable for use in circulation coins unless they are makign them for collector sets and even then, QC could probably be better. LOL

Hard to say exactly why.

I've assumed that difference was the aging of the die, though it's not clear to me if the typical business strike die starts out life shiny or matte.

The deep cameo proof coins lose the etched or hazy look of the cameo after they are worn and then become complete mirror like proof coins without the cameo.
So I am thinking that the hazy ones are from fresher dies maybe? Anyone know ?

Wow no one has chimed in with any info. I don't know where else I can look for this except here.

As I said a lot of things could be going on. We might be able to determine what the issue is if you have an example picture of what you mean.

There's always a big difference in circulation strike coins. They make them for commerce, not collectors and they don't really care how pretty they are as long as they are acceptable to be used as currency. The die deteriorate's over time and the amount of strikes performed until it's unusable and they usually push them to their limits, if there was a clash they try to take it out of the die and polish it to continus to maximize the amount of coins they get out of each die pair.

There's a bunch of reasons for a die pair to get reworked to fix them up to make it acceptable again and quite a few reasons just from normal wear and greasing for coins to have visual differences, strong or weak strike anomalies from power instability issues ect.

Seeing a picture of what you are referring to may help determine what category it falls into. It could even be storage issues at the armored carriers and moisture/humidity getting at their stock overnight as it sits there creating early toning/haze on the outer coins while the ones further down in the rolls or bags are protected by the outer coins from collecting moisture on the surfaces. I would thing that would be one sided though, and not obverse and reverse, and detectable on the rims even.
