I just received this lovely Order of the Sacred Treasure 6th Class, cased. On the reverse below the 6h rivet is the M mark of the Japan Mint, Osaka. The M mark is a nice, strong strike. In just the right light at just the right angle the ribbon looks to be a very, very pale blue. Otherwise, it looks to be a dirty/off white. Gold kanji grace the lid with the “Meiji/Taisho” stylization of 勣 (kun). Unfortunately this one did not come with a rosette. Oh well, you “can’t win ‘em all” as they say.
