Lot 203 Argentina SC#32 8c on 10c Green 1877 Surcharge Issue, A Very Good Unused Single, Estimated Value $20

A very good unused example of the 8c on 10c green from the 1877 Surcharge Issue. 2017 Gibbons cat. £160. Our estimate of the value based on the condition is $20.

A note about grading and estimated values is in order. We use estimated values rather than catalogue values where the grade of the stamp is other than that contemplated by the catalogue, or there is an unlisted variety. In deriving the estimates we divide catalogue values by 2 for examples without gum, unless Scott gives a separate no gum value, and also by 2 for each grade that is below the catalogue standard of VF for Scott or fine for Unitrade. So, for example a stamp cataloguing $300 in Scott that is in VG condition will be estimated at $75, if it has OG, or at $37 if it is unused. If it is a split grade, then I take the midpoint between the two grades, so that for example a VG-F stamp is about 1/3rd of the value of a VF example.
