20 Francs - Léopold III Pattern

Pattern coinage for Belgium's 1935 20 Francs was produced against a backdrop of acute political tension: Léopold III had ascended to the throne only in February of that year following Albert I's death in a climbing accident, and the new regime required fresh currency designs. Patterns from this transitional moment were struck in limited numbers for official approval, many never advancing beyond the trial stage.

The absence of any standard catalog attribution — no KM, Moreaux, or Laureijs number — places this firmly among the unattributed Belgian pattern material, a category notorious for incomplete provenance chains and disputed mintage figures.
