| Beschrijving keerzijde | Central composition featuring a schematic diagram of Babbage's analytical engine rendered in fine relief, illustrating the architecture of the first computer with labeled components: a central processor at the middle, flanked by circular nodes inscribed INPUT DEVICE to the left and OUTPUT DEVICE to the right, and a MEMORY section below, all interconnected by mechanical linkages. 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. The curved legend INVENTIONS OF THE MODERN WORLD runs along the left and upper periphery within a plain border. |
