Swiss 20 Francs Silver Proof

These Swiss 20 Francs silver proofs were struck using high-relief dies that brought out the subtle details of the Helvetia figure, a design element rare for circulating currency adaptations.

That precision came from the Swiss Federal Mint's insistence on proof quality, even for coins issued between 1979 and 1989. They used .900 fine silver planchets, a standard that ensured durability and shine, though production varied by year. Not every issue included these proofs; some years focused on commemoratives, like the 1986 one for the Swiss National Exhibition.

Mintage figures are spotty—records from that era aren't always complete. I've handled dozens over the years, and while myths persist about their investment value, they're solid collector pieces, not get-rich-quick schemes. As for the design, it's straightforward: a seated Helvetia on the obverse, with the denomination on the reverse. No frills, just good Swiss craftsmanship.

One oddity: the edge sometimes shows a reeded pattern that fools people into thinking it's gold. It's not.
