Watch List notes:

USA (San Francisco Mint), Seated Liberty silver trade dollar, 1877-S, crafted into a box dollar. 18.64 grams. As with the prior lot, box dollars were made using genuine Trade dollars found in circulation in the late 1800s, and it's been suggested some were sold as souvenirs during the 1893 World's Fair in Chicago. This example is fully intact and works by pressing down on the date, the interior is plain with a smaller circular compartment and three tiny screw holes. The coin itself grades VG+ with dark circulation cameo contrast.
