QV Sierra Leone SG58 2 1/2d on 3d dull purple & green very good MH. Type 12 surcharge overprint. SUPER RARE. CV £400
Only 148 possible (so likely only a dozen or so still in existence ), with this type occurring only once in the 10x3 setting, at R3/9.
Gibbons have one for sale at £175 with part OG and a thin. This one is better overall - just a rounded corner top right and no other faults. Two others on B1D for £250 and £850.
