What is this set worth? Are they rare?
The unused stamps are worth 20c each IF AND ONLY IF you affix them to a letter, and bring that letter to the United Nations office in New York to mail it. Otherwise, they are worthless.
UN stamps have been market dogs for decades. The fancy packaging might appeal to some but most would just regard it as unneeded bulk.
use them for postage within NYC ...UN stamp collection has only 1 key item and that is a
mini sheet issued in 1955....
Years ago in the 1970's it was in the hundreds of dollars but you can pick them up in
ebay under $10.00 . Just look at auction # 182537696923 in ebay......
Give them to the kids to plaster their school books with on the outside...sorry
the truth is the truth.
