Watch List notes:

USA (San Francisco Mint), Seated Liberty silver trade dollar, 1877-S, crafted into a box dollar. 18.64 grams. Box dollars like this were made using genuine Trade dollars found in circulation in the late 1800s, and it's 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 action of the hinge mechanism is smooth. Its interior is plain with a smaller circular compartment and three tiny screw holes. The coin itself grades VG+ with dark cameo contrast from circulation.

Estimate: $300 - $450
