In my oppinion it is TH-DDO-001. Here an brief description for: Cross Reference: VAM 3, 4 Description: Class V, Pivoted Hub Doubling. Doubling is seen on D of GOD, WE, chin, nose, eyelids, forehead, lips, chin, several rays in the tiara, and the hair behind the eyes. Die Markers: Obverse - None noted. Reverse - None noted. Comments: -This obverse was paired with two reverses. VAM 3 is a reverse that contains a medium 'D' mint mark. VAM 4 is a reverse with a small 'D' mint mark, and is worth much more.
Reverse has a medium D Thus VAM 3 1934-D VAM-3 - VAMWorld (ec2-13-58-222-16.us-east-2.compute.amazonaws.com)

From Flynn page 618 Top 20th Century Die Varieties. This TH (Hub doubling) it is pair with two different VAM's 3 and 4. In this case it is pair with VAM 3. TH prefix I think was attribute by Breen (not 100% sure)
