Watch List notes:

AUGSBURG (IMPERIAL CITY): Ferdinand III, 1637-1657, AR thaler, 1641, KM-77, Dav-5039, Schraubthaler or 'box thaler" with a single interior painted roundel, VF. Schraubthalers became fashionable toys in seventeenth-century Germany, with Augsburg a particular center of their manufacture. To make a schraubthaler, a thaler or pair of thalers was cut in half along the edge and hollowed out, with a groove added so that the two halves could be screwed or pressed together. One could place small pictures inside: religious symbols, portraits, or other miniature pictures were common.
