This time, the serials are on the obverse, and I've covered them, to be sure we don't have an easy solution.

The serialprovider today, is a 20 Francs 1956 from Belgium.

CLUES

The format of the serial is as follows: A23 456789

First digit is a letter.
Second digit is the value of the letter, and is also found on another place in the serial
The sum of the fourth, fifth and sixth digit is also a digit that can be found in the serial.
There are a lot of couples in this one.

The last digit can be found 1 time on the obverse of this banknote (outside the serial).
The sum of al digits (excluding the letter) is a multiplication of 2 prime numbers (Wikipedia).


RULES
Everyone can post their guess once a day, and every day at noon (forumtime), I will tell how much out of 9 or right. Please do not edit your postings. Post a new one every day, so others can use the guesses as extra help.

PRIZES
The person that guesses the serial gets this banknote, and maybe even some other goodies that are in my reach on packingday.
If you don't collect banknotes, guess anyway. Then I will send you some nice coins, and I'll send the banknote to the runner up of your choice biggrin.gif
Good luck!

Regards,

Jos
