Some of these stamps came from a swap, others I got from a pen-friend.
How can you not start a collection when you look at them?!
The most worthless stamp ever was issued in Hungary. In February 1946 the country issued a stamp with a value of 3000 pengö. This stamp was supposed to be the highest value in a series of postage stamps, but got issued a few months after the other stamps in this set. In the meantime the pengö lost so much of its value, thousands of these stamps were needed to frank a letter.
Also the first stamps without the name of the country; Magyar kir Posta; Magyarorszag; Magyar Posta
