Occupied Japan Vase 3" tall 6" round

This was brought back by my parents from a visit to Japan in the late 1940's. Just an interesting piece! If anyone knows more about this or the set of similar Occupied vases I'm going to show off next, I'd be very interested!
I have kids in grad school.....there may be a day I need to sell some of my collections....it would be nice to know approximately what they'd be worth, if anything.
This is all I really know:
1947-1952 OCCUPIED JAPAN/MADE IN OCCUPIED JAPAN ERA

The UNITED STATES occupied Japan from Sept. 2,1945, until April 28, 1952. The Occupied Japan backstamp Era truly began August 15, 1947 when the first shipment of Occupied Japan ceramics arrived in America. The U>S> Customs Bureau decreed in 1949 that Japanese goods could be marked"OCCUPIED JAPAN". "MADE IN OCCUPIED JAPAN","JAPAN"or"MADE IN JAPAN". Again, some were not marked at all. Occupied ware has its ardent collectors as well, but prices seem to be about equal to or (in some cases) lower than early Made in Japan
