used 1851 1cr. carmine on grey with good even margins, cancelled by a very fine complete strike of the rare mute 9 circles type of Castiglione della Pescaia (Sass. R); some slight traces of thinning. An exceptional example of one of the rarest Tuscan cancellations. Fiecchi (1975), Raybaudi (1980) and Enzo Diena (1985) Certificates. Photo
