Lot 302 Nigeria #262, 264, 303a 1969-1972 NSP&M Definitives and 30k Photogravure, Mixed Currency Franking on Registered Airmail to Finland, Net. Est. $25

Mixed currency registered airmail cover, sent from Uzuakoli on May 12, 1973. Franked with 6d NSPM, two 1/- NSPM and a 30k photogravure issue, paying 45k, overpaying the registered airmail rate to Finland by 1k (the 1/- stamps covert to 10k and the 6d to 5k). The stamps are tied by unclear strikes of a single circle Uzuakoli CDS cancel (4 GBP in Proud on cover).
The cancellations list in Proud for 4 GBP and the cover value to a common destination is approximately $16 applying Gibbons’ prescribed multiplier of 2 to the Scott value of $8.25 for the stamps off cover. Finland is a scarcer destination. So, the value of this cover, taking the destination, rate, franking and cancellations into account is $25.
