This piece has been described as the Liberty head obverse without star on coronet as used on J566/P627 combined with the Dutch 5 reverse of J464/P558 struck in nickel. We do not believe this piece exists as described. If J576/P632 does exist, then it should have the Tall 5 reverse of J467/P560 as the Farouk sale listed as part of lot 1800 a piece with the obverse of AW644 and reverse of AW554.
The image above shows both reverses for comparison. Again we believe the second reverse to be the one which should be on this piece.
