Maille - Anonymous Ypres

Ypres rose sharply as a commercial center in the late twelfth century, its cloth trade generating enough transactional volume to demand local small change independently of comital authority. These anonymous mailles, attributable to no single count, filled that gap — product of a civic economy outpacing its political administration. The absence of any issuing name was not oversight but deliberate ambiguity, sidestepping feudal coinage rights that were, in this period, actively contested across Flemish towns.

The Vanhoudt G2433 reference places this squarely within a transitional phase before Philip of Alsace's monetary reforms tightened comital control over Flemish minting.
