How much were Zingraff Paris opera glasses worth in their time?

Prices for Zingraff Paris opera glasses varied widely in the late 19th century. Simple brass models could sell for around 8 to 12 francs, which was roughly a day’s wage for a skilled worker in Paris during the 1880s. More decorative versions, with enamel or mother-of-pearl, could reach 40 francs or more. Luxury editions sometimes included gold plating or engraved monograms, raising prices closer to 100 francs. Adjusted for modern values, that range would equate to roughly €40 to €500 today. These prices show that opera glasses were both practical items and status symbols. Wealthier buyers often selected ornate designs to match evening attire. Surviving catalogues from the 1890s list multiple styles under the Zingraff name, suggesting steady demand. Condition plays a large role in present-day value, with intact lenses and original cases increasing collector interest. Auction listings in recent years show some rare examples exceeding €800.
