| Reverse description | Plain bronze field bearing the British Royal Mint mark at centre, presented within a rounded rectangular cartouche and depicting the Tower of London motif with two cross-topped turrets and a crenellated parapet, executed in fine incuse relief. As is characteristic of a planchet trial strike, no denomination, legend, or peripheral inscription appears anywhere on the surface, the entire field serving solely to test the blank's metal properties and striking characteristics. |

| Additional information |
Planchet trials of this kind were produced ahead of the 1965 Bahraini coinage reform to verify that blank specifications — weight tolerance, alloy consistency, and striking pressure — met mint standards before dies were committed to production runs. Bahrain's coinage at this period was being developed through external mints, and such trials rarely entered any official record, which is precisely why documented survivors are scarce. Most were destroyed after approval.
