New Serial number

hey i just got a stack of 20s, uncirculated and the serial number starts with EWH (one of them is EWI) have these not been added yet? Of do i have a stack of phonies? When will it be added?

Ive got both before. Also have entered them.. DOn't know why you're having problems (are you?)..

Nope i tried a couple of other bills and they worked fine. Ill try and enter them again now.

Nope I just tried 6 of them. None of them worked! I keep getting this message ERROR: You have entered an unknown serial number prefix. If you feel this to be an error, please contact the site administrator If DR doesnt respond to this I'll give him an email. Well Im out for the weekend so I hope when i come bac i can enter them.

DR could you tell me whats wrong? or should i email you? Thanks,
Wes

Email me the specific serial numbers. Perhaps the bill has been entered before or something.
