💷 Valuation & Price Guidance (UK Market)
Swiss slogan cancels from the 1950s—especially anniversary postal slogans—are modestly collectible. A commercial-use cover (not philatelic) adds interest.
Typical market value: £4 – £6
Occasional higher sales: £7 – £9 for clean, well-struck cancellations.
Your cover appears clean with a clear slogan, so sits toward the upper-middle range.
