What you get • Browse 17,000+ marks four ways: by letter, by object, by animal, or by shape. Whichever lane matches the punch in front of you. • American silver covered properly. Gorham, Towle, Wallace, Reed & Barton, Tiffany, coin silver, and 249 Navajo and Native American smiths that most references leave out. • British date letters for London, Birmingham, Sheffield, Edinburgh, Chester, Dublin and Glasgow. Pin the exact year a piece left the assay office. • Maker's marks show town, working years and metal standard at a glance. Useful when you are telling a Hester Bateman from a 1920s revival. • Sterling or plate, settled fast. EPNS, EPBM, Britannia, 800 and 900 laid out side by side. The question every estate sale turns on. • Snap a punch and match it against the reference library on your device.
