Open the Reverse J8. Click on the Obverse thread associated
with J8. Compare your obverse to the photos provided. One
marker I remember (without returning to the thread) concerns
the cloven left-end of the base of the E in DEI. (On your photo
this area had too much crud to confirm.) Verify the other markers.
If congruent, Obverse 491, Reverse J8.
A typo in my previous thread. Change Reverse to Obverse 491. Sorry.
