| Obverse description | Portraits of William Wyatt Bibb, the first governor of Alabama, and Thomas E. Kilby, the current governor. Twenty-two stars are arranged to each side of the portrait. Some coins were struck with “2X2” in the right field above the stars. Although this was intended to be a scarcer variety, ultimately the number of plain and “2X2” coins were very close. |
