A paperweight similar to yours is shown on page 198 of Leslie Pina's Fratelli Toso. This page is from a 1960s JI Co catalog. Toso made a lot of the weights that JI Co (Jordan Import, NY) imported to the USA. The "book value" of a 3" weight like this is about $100. eBay values tend to run $25-35. These weights are fairly common. Toso made a good number for export.
