Are one or both of these counterfeit?

Someone just emailed these images to us asking what was going on. The only difference is the plate serial number. I honestly don't have an answer for him. Can anyone here offer some input?
Thanks in advance!

It appears some wise guy erased the last serial number on each note. Maybe to possibly create a pair of faux error notes.
Of course. Foolish of me not to realize that. Thank you, @mbwizkid!
Abrasion marks show the serial numbers' last digit removed from two outta the same pack.
dont put it on ebay for $1,000,000 now
Bleach or solvent and a q-tip. Peace Roy
