Order of the Sacred Treasure
Case Inscriptions
The orders and some medals had lacquered wood presentation cases. There
is a great variety of cases even those made for the same medal. The
inscription may be one or two rows, it may be in gold or silver, and there may be
variations in the kanji strokes.

The cases may have a push-button latch, a hook latch, or no latch at all. Some
cases are thick; some are thin. Some have protruding hinges; some have
hidden hinges.

Supposedly one can determine the period of the case by noting these
differences, but I can find no resource where this information is available.
Peterson mentions nothing about this issue in his book.

I hope to study more Japanese sources and note anything about the cases
here. Does anyone have any information, either second-hand or source
material? I will list ideas as they are presented.
