VALUTATION OF THE CANCELLATIONS (**)Cancellation Prephilatelic 1st issue 2nd issue 4th Sardinia Revenue SD - straight block letters - R1 - R1 - - - SD - straight block letters - blue - R4 - R5 - - - LOV - horizontal / vertical lines - 8 - 7 12 - 11 12 - 12 12 - R1 (**) The evaluation is expressed using a double system: in white color you can find the score indicated in the Sassone catalogue and in green color the one that the experience of the collectors consider coherent with the availability on the market. I want to underline that the alternative valutation DOESN'T want to replace the one from the catalogue but it only wants to give you a personal esteem, coming from decades of specialized collecting and costant research of this kind of cancellations.
The score system used there is the same of the one present in the Sassone catalogue (from 0 to 13 and from R1 to R5)
