10 Francs Reeded edge, pattern

This is a pattern strike, not a circulated or even officially released type — Swissmint produced it to evaluate a reeded edge treatment for the 10 franc gold denomination at a time when Switzerland was weighing design and production standards against its Latin Monetary Union obligations. The LMU had strict specifications governing gold coinage among member states, and edge treatments were not a trivial aesthetic choice. Whether this variant advanced beyond internal evaluation is unrecorded in the standard literature.

Divo/Tob pattern numbering places it firmly in the documented Swiss pattern sequence, but surviving examples are extremely few.
