PALM BEACH COUNTY, Fla. — Now's a great time to keep a close eye on your pocket change.

From now until April 28 at 11:59 p.m., more than a million new and vintage coins will be dropped into circulation by the U.S. Mint, as well as coin dealers and collectors as part of the Great American Coin Hunt.

"It's going to be coin dealers like myself getting kids interested in the hobby," said Gary Tancer, owner of the Coin & Jewelry Gallery of Boca Raton, Florida.

Over the next several days, dealers and collectors will visit businesses and drop off bags of rare coins so they can be worked into the day-to-day cycle of commerce.

Tancer said he plans to cycle in coins like wheat and Indian pennies, Eisenhower dollars, and buffalo nickels from as far back as the 1930s and '40s.

"It's a great way for kids to enjoy the hobby with their family," Tancer said. "It's just getting everybody interested in the hobby again. It's a great hobby."

Tancer said the value of rare coins has decreased over the last decade, so now is a good opportunity for children to put together a collection of rare coins at a low cost.

The event, sponsored by the American Numismatic Association, is being called the biggest coin drop in American history.
