This is a truly magnificent Gambia SG 4, the 6d Pale Blue, issued in 1869.  This is the VERY RARE SHADE!!! 

This one has rich color, full margins all around, and full original gum. It would be a Gem save for one small problem - it has a very small hole  in Queen Victoria's head!  Even so, it is a still a truly wonderful item!

It comes with an RPSL Certificate of authenticity!

It's valued at L3250 in the Stanley Gibbons Catalogue.

This item is over $100 USD so I will ship it using Priority Mail in the US, and Registered Mail overseas.  This is to ensure that it reaches you in a safe and timely manner, and includes tracking!
