150 Beken - Ooteghem Otegem

Belgian municipal token issues of the early 1980s were produced under a loose framework of local commemorative licensing, with communes contracting private firms — most commonly Fonson or the Monnaie Royale de Belgique — to strike small-run pieces for anniversaries, fairs, and civic occasions. Otegem, a section of the municipality of Zwevegem in West Flanders, falls squarely into this tradition. The "150 Beken" designation almost certainly marks a 150th anniversary of a local waterway administration or drainage authority, a common subject for Flemish rural commemoratives of this period.

Patinated bronze strikes of this type were typically applied chemically after minting to distinguish presentation pieces from plain-finish versions — the GMJ suffix "a" likely denotes exactly that distinction.
