For someone that puts a lot of importance on words you don't seem to understand this one.
http://en.wikipedia.org/wiki/SovereigntyThe political countries that other coins would represent are not sovereign nations.
Iceland is not a sovereign nation?
Cyprus is not a sovereign nation?
Romania is not a sovereign nation?
I don't think
you understand what the word means.
I'll counter your Wikipedia link with this one:
