| Obverse lettering | JOSEPH PRIESTLEY |
| Reverse description | The reverse depicts Priestley leaning over a laboratory bench, conducting his famous oxygen experiment, surrounded by period scientific apparatus including a burning lens, flasks, and a retort over a flame, all in high relief against a polished field. The curved legend BICENTENNIAL OF THE DISCOVERY OF OXYGEN arcs around the upper portion of the field, with the dates 1774-1974 below it. An engraver's monogram appears near the lower right. |
