The find came on the east coast of Florida near Wabasso Beach.
Brent Brisben was searching an area just six feet deep and a few yards from shore when he began finding gold coins.
Before he was done Brisben dug out 48 coins worth approximately $250,000.
The eastern shore of Florida is known as the Gold Coast for a reason.
Ships loaded with treasures of all kinds were lost along the coast for over 100 years and from time to time the ocean gives some of that booty back.
The coins found were all dated between 1697 and 1714 and were near the spot where records show 11 Spanish galleons sank in a 1715 hurricane.
Captain Greg Bounds told WPTV "it sounds glamorous, but it can take years to find anything."
"A lot of times, its beer cans, fishing weights, just garbage," he chuckled.
