Nice Set, Yes Occupied Japan items are very Collectible, and it sounds like you have almost a full set too. Missing only a Saucer and two cups. Chris is right about the age, only during those years was items marked as Occupied Japan. If you wish to find the pattern, you can try going through the many patterns by Meito at Replacements.com
http://www.replacements.com/china/MEIIMG01.htm I would say you are looking at around $300.00 to $500.00 for the set. Selling can be some what a problem though, not easy to Ebay, and would take some time to sell locally for the most part. The set is a Fancy Set, not Extra Fancy or Plain, so this will help a bit too. Thanks for sharing
