I found the 2019-W American Memorial Park quarter at the Main Street Casino in Aug 2019 from a video poker machine.
Some of those machines paid out in quarters.

The other 4 of 2019 were found in roll searches in Southern California.

Since the pandemic shut down, the banks were unable to get new quarter rolls, so I was able to find only two of the five for 2020, American Samoa and Salt River.

I doubt if I'll ever find the other three.

I have an extra Salt River if you're looking to trade or buy.
