Rwanda-Burundi 15.9.1960 P-6 PMG Very Fine 30 500 Francs
A scarce and popular type from this short-lived issuer. Difficult to find in problem-free circulated condition as seen here. Most of these were redeemed after Rwanda and Burundi issued their own currencies, with some others were overprinted by both countries for use in Rwanda and Burundi only. This one escaped both those overprints, and it would be perfect for inclusion in an advanced Africa collection.
