The Chicken McNugget, three years old, holds an apparently striking resemblance to America's first ever president George Washington.
Yesterday's dramatic auction attracted over 70 bids, before being sold for the $5k sum to an unknown buyer.
Rebekah Speights and her husband placed the frozen chicken piece online last month.
However, her plan was nearly ended after eBay halted the auction citing food regulations. The company later reversed its decision.
Initial bids of $350 (£223) were considered newsworthy.
