Italy - 150 Years of Universal Postal Union (UPU) 2024 #UPU150 #150UPU

A little late but it's never too late ... Italy issued a stamp to commemorate "150th Anniversary of UPU" on 21 November 2024.

Italy Stamp on 150 Years of UPU - 2024

The denomination of the stamp is a B zona 3 50g and is valid for international Oceania 50g. It is probably the most expensive stamps issued for "150 Years of UPU" by any country.

I wonder why the thematic stamps of international interest like UPU150 are often of very high value (4,95€ in this case)! Probably because of the collector value of the stamp! 

What do you think why Italy UPU150 stamp is so expensive?
