Wall Street may be an icon of New York, but for a hands-on experience of finance, you’ll have to get your kids behind closed doors. On your next family outing, head down the block from the Stock Exchange to the Museum of American Finance. The little ones will be impressed right off with the space, a grand marble room that housed a historic bank. Interactive displays make the history come alive. Kids can handle coins, and use an ultraviolet light to reveal the secrets in a modern bill. They’ll marvel at bygone technology like stock tickers and clunky old computer terminals. The history of money will be a big hit, from its humble wampum bead beginning, through wooden nickels and counterfeit bills. Let your offspring fantasize for a while about what they’d do if they got their hands on a $10,000 bill. And what kid isn’t impressed by the sight of a 60-pound bar of gold, especially one pulled from an ancient shipwreck? Another treasure to check out is a Monopoly set worth millions—the board is solid gold, with color provided by 165 rubies, diamonds, and emeralds. Despite all the focus on money, the museum doesn’t always accept it: look for free Saturday admissions with family activities, and maybe a historical stock certificate giveaway as a souvenir for your little future tycoons.
