Hello friends, yesterday I received a gift from a fellow member of the forum a crypto stamp doge and I really liked it.
I am writing this post so that you can help me to know how many different types of crypto stamp exist and their characteristics both in the physical versions and in the ethereum network.
That is, if someone has a catalog where all the versions appear. Thank you very much for the help.
