The treasury seal and serial numbers are printed in a single pass so if the seal is missing the serial numbers should be missing as well.
Assuming that's the case, look on the back of the bill to see if the seal and numbers are there instead of on the front. If so, you have what's called a flipover error; I've seen these bring $500 or so at retail. If the seal and numbers aren't on the back the bill missed one of the printing steps. Its retail value is less but could still easily be over $150.
In any case because almost all errors are by nature non-standard, you'd need to have an in-person evaluation done by an expert in paper money errors to get a more exact idea of its value.
Up to a whole $2. The Treasury is still making series 2003 bills.
Yes, the Treasury printed $2 bills in the 2003 series, also 2005 and 2008.

, do not know about the twenty. I recently sold a 2003 A five dollar bill with no treasury seal for $70 on ebay.
$1.00
There were no 2003 Australian Ten Dollar star notes issued.
A 2003 American Eagle Bullion Dollar in MS65 condition is: $24.00.

Please check your bill again. All $100 bills printed from 1969 to 2009 had green ink. In any case a 2003 A bill is too new to have any extra value.
It is worth face value unless it is uncirculated.
yes, five dollars
