If you actively search quarters you will find them, if you just check pocket change, it will be luck of the draw and a hit or miss endeavor. I'll tell you this though, the longer you wait to look for them, the hard it will be to find them with the newer coins each year added to the mix, and the condition will get worse also as they circulate.
I am certain if you search even $100 in quarters a week, you'll come across one here or there over time still. might even get lucky and find 2019 or 2020 whole rolls still. in a year or two those chances go to nil of finding whole rolls of 2019 or 2020 P or D to look through.
