Baltimore! The very word implies numismatic excitement. Three times a year, Whitman Publishing LLC presents the Whitman Coin & Collectibles Expo at the Baltimore Convention Center. We are honored to have maintained our position as the only official auctioneer of this dynamic convention since its debut. The Expo features hundreds of dealers, thousands of attendees, and a venue that is very pleasant. Located in the Inner Harbor area of Baltimore, the Convention Center is close to fine hotels, restaurants and shopping.
