Obverse 2 by Marsh (1859 - 1871): The bust is slightly larger than on earlier coins, the Queen's hair is noticeably nearer to the G in GRATIA, and the small strand of hair that came out from behind the bun has been removed.

Crowned and garnished shield quartered with the arms of England (1 & 4), Scotland (2) and Ireland (3); around, BRITANNIARUM REGINA FID: DEF:
A small dot is shown just above the centre of the crossed lines that divide the Ensigns Armorial (unlike coins before 1859).
Die number located under the shield.
Known die numbers (as per Marsh 1982): 1, 3, 4, 5, 6, 33, 35, 36, 37, 38, 40, 41, 42, 43, 44, 46.
