Don't have a picture available at the moment, but I got a Series 2009 $20 in change today with a serial number of JE11700509*. Condition is lightly folded due to being in my billfold, but otherwise uncirculated.
Any reason to hold onto this? I save any and all $1 star notes I find, but $20 is a bit much to tie up forever if it's not actually worth more than face value...
