I just found my first 2020 W in change. Probably grades at XF. Numismedia lists them the same as the other mints and NGC and PCGS don't list anything for grades that low. However I'm seeing quite a few people claiming they're worth more including some shops. So is there really any premium on these at XF and AU or not? And if so about how much?
They're a somewhat rare novelty and probably worth a small premium. Having never found one, I might pay a buck or two at the flea market for one, although nice uncirculated pieces are easy to find.
As with anything else, it's what a buyer is willing to pay. I sold one fresh from a roll at a local coin club meeting for $20.
