The Bank of Ghana (BoG) has attributed the altered appearance of Theodosia Salome Okoh on the new GH¢50 Heritage Series banknote to technical adjustments made during the design process, including replacing her signature head-tie with a hairstyle common to her era.
In a press release issued by the Communications Department on November 13, 2026, the central bank confirmed that the portrait was developed from multiple photographs of Mrs Okoh and not from any image of her sister, Dr Letitia Obeng.
The bank explained that the selected photographs were used to create an engraved artistic representation suitable for banknote printing.
However, during this process, certain modifications were necessary to satisfy the strict technical and security requirements of currency production.
"These adaptations, unfortunately, contributed to the perceived differences in her appearance, and to the image bearing a close likeness to Dr Obeng," the statement acknowledged.

Public debate
The bank's clarification follows intense public discourse sparked by a social media post from Dr Eddie Obeng, nephew of Theodosia Okoh and son of Dr Letitia Obeng. Dr Obeng expressed astonishment that his mother's likeness appeared on the note instead of his aunt's, writing that the resemblance was unmistakable.

His post prompted widespread discussion, with many Ghanaians questioning how such an error could occur on a national currency honouring a revered figure.
To address the controversy, a Bank of Ghana board member, Beatrice Feehi Annangfio, issued a statement on Facebook explaining the design process. Her post was widely shared by government communicators and some media outlets.
