Up until today, I've only been able to get 2 rolls of each denomination per bank. The last bank stop I made today said they were now able to do unlimited! I picked up $300 in quarters ( all the cash I had on me), made it home, and have made it through 19 rolls so far, 90% being 2020 MBR Denver's. So far I've found 4 W's.
Ended up going back to the bank, picked up the rest of that box and then picked up another box, which looks to be all 2020 Samoa's. Will post any updates of additional finds.
