This is an obverse hub trial, in copper, for the design used on J754-J759A/P838-P844 with a few exceptions.
Liberty is not inscribed on the headband and the date is below Miss Liberty instead of the scroll with "In God We Trust". Unlike JA1869-9/P3377, the star on Liberty's headband points correctly to the "O" in "Of" instead of the "S" in "States".
It is believed to be unique and is ex Nagy, Cox, ANS.
