Unknown Die Pair Usage: Kalakaua Centenntial Dala Obverse Die + Unknown Reverse Die

Below is an image of an unknown die pair usage from The Hawaiian Mint.

The coin is 39 mm bronze.

The obverse die was used extensively with gold, silver, and bronze strikings.

The reverse die is currently unknown and has never been seen on any of The Hawaiian Mint products.

This is the  first specimen I’ve seen with this die pair combination. This maybe in fact a pattern coin. I’ve checked my Hawaiian numismatic  resources and this die pair should not exist.
