I want to know if a $20 bill that has 8888 in the serial numbers is worth anything?
It really kinda depends on what the other numbers are and the condition of the bill.
If the other numbers make a creative pattern or number sequence then it might be but just having 4 eights together with other random numbers.
TPH wrote an article and made a video here about $1 bills worth money but the same rules would apply to $20 bills.
