Q: We have six silver spoons that have been passed down in our family. They’re embossed with a crown and “1848-1898” on the front and an eagle and shield on the back. Members of my family were glass blowers, cutters, and designers in what was originally Austria-Hungary. My great-grandfather created glass eyes for soldiers during World War I. They were chosen by Kaiser Franz Joseph as the best. My great-grandfather was invited to Vienna and this is where these spoons came from. I’d like to know if they are rare and what their value is on the antiques market.

A: Your spoons were made in a mold that created the imperial crown and coat of arms for Emperor Franz Joseph I who reigned from December 2, 1848, to November 21, 1916. The spoons commemorate Franz Joseph’s Golden Jubilee, the 50th year of his reign. Most souvenir spoons sell for $5 to $10, depending on rarity and silver content. Sterling silver spoons sell for more than silver plate. Spoons with enamel decoration bring the highest prices.
