I purchased a complete bronze set in original wooden display  box.  These medals are individually listed in Medcalf & Russell: 2M-500 through 2M-560 (every 3rd increment is bronze).

Medcalf & Russell (page 129) indicates to look at page 121 (error…should be page 123) for complete Pearl Harbor Commemorative medal sets. No complete bronze set is listed…

Complete set  (and display box) was purchased for $20 (not a typo).
