Hey guys somewhat new here but just went to the ATM and got some interesting serial numbers on some 2013 $20 bills and I wanted to see if they're something worth holding onto or are just spenders? They appear to be uncirculated other than by me, the serial numbers start at 64322234 consecutively through 64322241. The first one sort of jumped out at me (64322234) and I know that some serial numbers carry some appeal so I thought I'd check before I go and spend them!
Even new consecutive $100 dollar bills are common, unless you want to save them for you great great grandchildren. They might have a $10-$20 premium then. Of course with inflation it maybe $25-$50, but the hundred dollar bill will be worth less as well. If the world is still here, I would guess you need to hold them for at least 100 years to off-set inflation and make their buying/resale value better than it exists now. Twenties aren't worth the wait.
