I just posted an ANA journal entry of this discovery. A few items are still being withheld due to a US copyright submission.
Created a blog at my NGC Journal. It can see seen at
Excellent NFL brass coin with enamel.
Busy with work, but I’ve been acquiring specimens.
It took some time for me to figure this out (slaps forehead). I should have been more observant. The initials LB stand for designer Luigi Badia.
I know of two RHM products with his initials on the obverse.
1992 dated Princess Kaiulani 1/10 oz silver
1991 King Kalakaua Akahi Dala 1/oz silver
Here is a plaster model of the obverse die with the LB initials.
