Today's side deal gets you two one-day admissions (a $12 value) and a world mint passport (a $9.95 value) to be used in one visit at the World's Fair of Money (a $21.95 total value). The fair takes place August 10–14 at the John B. Hynes Veterans Memorial Convention Center. While you can use this Groupon on your choice of day, please note that Tuesday, August 10, has limited hours.

The World's Fair of Money is a huge show sponsored by the American Numismatic Association devoted to the exhibition and history of currency. With more than 1,000 of the nation's most prominent coin dealers displaying their gargantuan inventory of coins, paper money, medals, tokens, and more, the World's Fair of Money is equal parts coin show and family-friendly activity. While kids are engaged in getting their world mint passport stamped at each international mint location along the fair's promenade (they'll receive a coin from each participating country, including Australia, China, France, and the Isle of Man), serious collectors can take in the educational seminars or the fair's museum-quality exhibits presented by the Smithsonian Institution, the ANA Edward C. Rochette Money Museum, and private collectors. Whether flying solo or traveling with the entire family in a tiny silver car or accelerated thimble, the World's Fair of Money offers a pleasing sight for every visiting numismatist.

Children under 12 and ANA members receive free admission to the fair.
