This is a fantastic group of Rhodesia stamps from April 15, 1909.  They are SG 100-103, the 1/2d - 2 1/2d with RHODESIA Overprint in BLACK.

This includes blocks of 4 for the 1/2d, 1d, and 2d stamps, but a pair of the 2 1/2d. 

All of them are in Very Fine to Extremely Fine Condition.  The blocks of the 1/2d and 1d are both Mint Never Hinged, while the 2d and 2 1/2d both have a right HR on the top pair.  All of the stamps have their Original Gum intact.  They are valued together at L150+ in the Stanley Gibbons Catalogue.  A truly AMAZING set!
