Akçe - Mehmed I 816AH knotted variant

Mehmed I spent nearly a decade fighting his brothers for control of the Ottoman sultanate in the civil conflict known as the Ottoman Interregnum — a period during which multiple claimants struck their own coinage simultaneously, making attribution a persistent headache for specialists. The knotted variant of his 816 AH akçe is distinguished by a small ornamental knot device introduced through die-cutter preference or workshop convention rather than any administrative decree, and it does not appear consistently across all striking locations.
