PMG 35 Choice Very Fine (1915805-010).
P.55 - F.A46.04.
Alphabet J.1703 - number 675, this is the last year 1873 for the type! The 20 francs is very often named "Chazal" in reference to the engraver of this 19th-century banknote, always sought after in superior states of preservation. Fewer than 20 examples referenced in the PMG population database (the majority of which are always presented in VF to VF+ or lower than PMG 25).
