Denier - Anonymous Siege coinage

The anonymous deniers of the Kingdom of Jerusalem were struck without royal attribution by deliberate policy — the Crusader states relied heavily on trade with Muslim merchants and Byzantine intermediaries, and coins naming a Christian king were commercially unwelcome in much of the eastern Mediterranean. Anonymity was economic pragmatism, not administrative oversight.

Metcalf's classification of this type within his broader Crusader coinage corpus placed it firmly in the 12th century, though the precise mint — whether Jerusalem itself, Acre, or another Latin stronghold — remains unresolved in the literature.
