 1861 - 1gr black-grey, on cover from 'MILANO 11 APR 61', within the city. Extremely rare use of this value outside the territory of the Neapolitan Provinces, at the correct rate for the district (1 grano = 5 centesimi). A great rarity of the section. E. Diena and Serra certificates: 'Outside the Neapolitan Provinces only one other loose used example is known, "Genova Mar 62"' (Sassone 19a)
