The Keusch Collection of Assay Commission Medals was the greatest and most extensive collection ever formed of these esoteric and rare medals. We were honored to present that cabinet at auction in November 2008. This August, we are fortunate to be able to offer again a large group of these medals from a private collector who bought extensively from that sale. Many are exceedingly rare and the finest known of their types. View the entire offering here.
