This is a Zanzibar Provisional SG 22 DHI, issued in 1895-98.  It has a 2 1/2 Type 2 IN RED.  This is a RARE stamp, and it is in Fine to Very Fine Mint Condition with Original Gum.

A couple of things to note with this stamp are that, in the 2 1/2, the 1 is inverted.

If we examine the black Zanzibar text at the bottom of the stamp, we can also see that the 2nd lower case z is rather small, and an inverted q was used in placed of the b in Zanzibar.

SG 22 DHI is valued at L1100 in the Stanley Gibbons Catalogue.

This lot is over $100 USD so I will ship it using priority mail in the United States, and registered mail overseas.  This is to ensure that it reaches you in a safe and timely manner, and includes tracking!
