Set of 12 Sterling Silver Shell-Shaped Place Card Holders

A lovely set of 12 sterling silver shell-shaped place card holders. Each one is unclearly stamped “_?_uskow sterling” with the maker’s mark on the underside of the base.

The holders each measure 1 inch tall and 1 inch in diameter. All are in very good condition with typical usage scratching.
Each has a nice base weight to keep the cards upright and not tip over.
