Looking at the link, my question is: what's the difference between "stamped" and "unstamped"? I'm not familiar with Austria's postal service, but this sounds like either canceled or uncanceled to me. Can you clarify that, OP? I'm very interested in buying some of these.
Stamped means they will strike with a postage strike and unstamped is a mint stamp..thats if they follow the USA terms IIRC.
I have sent them an email and will post what they reply with
And since you are interested in stamps...this is the very first LOADED BTC stamp ever made and postally used! https://bitcointalksearch.org/topic/m.20957878
WOW Congrats! It's a very nice idea!
But There is a difference with "Crypto Stamp" of Austrian Post, since a customized stamp is like a "private issue".
You will never find in an official catalogue, you will never be able to buy (only the first owner ).
yes it's absolutely rare, but it's very hard a collector could pay too much for a sort of "un-official" stamp.
Anyone can make a infinite series of unique pieces...
But it's even a nice idea probably one of the best usage I have ever seen of personalized stamp.
