Check the listing for details. Antique Danish Silver 830. Cigarette Case. Made in Denmark. Listed at 349.00 USD. From about 1911, many Danish silversmiths shifted to 830 fineness for practical reasons (harder alloy, better wear resistance), especially for everyday luxury items like cigarette cases. Earlier pieces might use 826, but 830 became standard mid-century. This item example features a classic engine-turned (or guilloché) pattern across the lid and body — fine, parallel, machine-engraved lines creating a ribbed or textured effect. This is a popular Art Deco and mid-20th-century style (roughly 1920s–1960s), giving a sophisticated, geometric shimmer without ornate chasing or repoussé. It’s understated yet elegant, often seen on Danish, Norwegian, or broader Scandinavian pieces from that era. Measures 3” x 5” and weighs 5.17 oz or 146 grams. Engraved.
