Didn't know either for those varieties, also didn't know it doesn't circulate...I guess value is too small.
What that book says about all those commemoratives listed in Krause catalog? I simply don't understand why some modern fantasy coins are listed there, for instance coins of Somalia, Congo, etc...coins that not only are made for collectors, but they're made to confuse them to circulation pieces, while not even being issued by any form of government. And for some of those eyes are shut completely.
Also I didn't quite understand older 1 star and 2 star coins...were they given to foreigners as exchange upon arriving in country or they were given as souvenir sets to them. I understood the latter, but not sure.
