Stack's Bowers Galleries' annual Global Showcase Auction of World and Ancient coins will feature nearly 5,500 lots, encompassing an expansive range of material across nine sessions, with a high estimate that exceeds $10 million. The live auctioneer-led sessions will be held August 25, 26, 28 and 30, with the internet sessions taking place September 2-5.

The Richard August Collection offers interesting and desirable selections from the cabinet of this respected numismatist and familiar presence at coin shows, especially around New England. Among his world coin holdings, Mr. August's British Isles coins are particularly notable for their quality and include a Great Britain 1668 5 Guineas and a stunning 1601 British Crown graded AU-55 by NGC. Also worthy of mention from the Richard August Collection is a charmingly struck and detailed Bolivian "Royal" Presentation Cob 8 Reales.

The Hough Family Collection comprises exceptional American rarities as well as stunning European gold issues. Highlights among the world coins include a tremendously rare Commonwealth 50 Shillings 1656 Pattern graded Proof-62 Cameo (PCGS), an extremely rare 1643 Triple Unite graded MS-61 (PCGS), and a remarkable PCGS Proof 63+ 1826 Great Britain 5 Pounds.

A group of rare and ephemeral items from the turbulent period of Napoleon Bonaparte's rise and fall will be presented in Part IV of the Richard Margolis Collection on August 30. Fascinating pieces include a rare 1793-M Louis d'Or de 24 Livres, an impressive 1815-A Gold 40 Francs Essai, and a 1786-A Silver Ecu de Calonne Essai, among other French numismatic-related lots.

Aside from the major collections, spectacular individual lots include a PCGS MS-62 certified quadruple thick 1742 2 Talers from Germany and a striking Philippines countermark applied to a French Ecu of Louis XV (a rare host for the countermark). Ancient numismatics offers several eye-catching lots, including a well-struck Ch F Strike: 5/5 Surface: 4/5 Marc Antony & Octavia AV Aureus, as well as an appealing AU Strike: 5/5 Surface: 3/5 Syracuse AV 100 Litrai from 400 B.C. Also notable is a rare Judaea AR Half Shekel certified by NGC as EF Strike: 4/5 Surface: 4/5, which would be an exquisite addition to any advanced Judean collection.
