40l bistre on greenish (pos.141) with different (calligraphic) "4" on control number (Kound. 48.1), tied by "9" Patras cds. Touched at places at top left and at right. A different type of "4" used, already in hands at the National Mint either because the normal "4" were finished or accidentally place among normal "4"s. ONLY TWO COPIES KNOWN, BOTH FROM POSITION 141 USED IN PATRAS. A very impressive, great rarity. (Hellas 36bNe).
