After Lucy's son Jerry finds a penny worth fifty cents, Lucy and Viv comb through thousands of coins borrowed from the bank until they find one worth $16.50. Among the items Lucy and Viv offer to Mr. Mooney as collateral, taken from their purses, are three earrings, a collapsible cup, a Mickey Mouse watch, a doggie bag of spaghetti and meatballs, a jeweled garter, Jerry's bronzed baby shoe, and a high school broad jump medal.
On the way home, Lucy drops the valuable penny down a storm drain. The two ladies now have to disguise themselves using worker's uniforms to retrieve their coin without suspicion.
