P.135a - F.49.07.
Alphabet C.63 - number 25815, this type is very rare as it is the only known example for alphabet 63 to date. No other specimen referenced between alphabet 64 and 68 for this date, but above all no other bill found between 69 and 86, only the discovery of alphabet 87 and a new date for the type in non-overprinted form of 30-10-1958, which realized a price of 10,000 euros at Olivier Goujon Numismatique (OGN).
Very nice, with numerous pins on the left side and a small tear at 12 o'clock. TB+.
