Above the diagram, within a circular frame, appears a draped bust portrait of Charles Babbage facing slightly left. To the right of the portrait the inscriptions CHARLES BABBAGE and 1792-1871 are engraved in the field. The date 1823 and FIRST COMPUTER appear in the lower portion of the diagram, with the denomination 1 CROWN at the very bottom of the coin.
