A huge collection of treasure lost in a shipwreck before being uncovered by a metal detectorist has gone on public display for the first time.
The treasure dates back to 1583, when a valuable cargo of grain was sent to Spain by ship. A violent storm meant both the ship and the gold sent back as payment were lost on its return.
Peter Hughes, 69, spent 21 years uncovering hundreds of coins and other items with his metal detector, after storms blew away the sand concealing them on Margam Beach in Neath Port Talbot.
He described the day he first struck gold, in 1996, as "just incredible".
"When I lifted the coin from the sand, and the sand fell off the coin, it glowed like the sun in my hand," said Hughes.
"I was overwhelmed, because I saw the figure of a saint holding a ship, Saint Vincent, and I thought it was a token at first.
"But when I turned it over and saw the shield of Portugal, then I knew it was a coin. I was overwhelmed with excitement, the thrill was unbelievable."
Hughes' finds include several historical gold coins from the reign of Ferdinand and Isabella of Spain.
There is also a Boatswain's whistle, and a combination lock from one of the ship's wooden chests - the lock's code is still to be cracked.
It is estimated that only a quarter of the money that was aboard the Ann Francis ship, which was caught in the storm on 28 December 1583, has been discovered.
Hughes said he initially did not know what to do with his discoveries, until he contacted Amgueddfa Cymru (Museum Wales).
"The objects and the treasure belong to the people, and belonged to the heritage of Wales," said Hughes.
"The Pirates of the Caribbean come to mind when I look at it," he added.
The treasure has now gone on display at the National Waterfront Museum in Swansea.
Amgueddfa Cymru said the stretch of beach was now a protected site to preserve any other potential remains of the ship.
"Not only are the coins and artefacts spectacular, but they are backed up by a wealth of contemporary records that bring together stories of sailors and lords," said the museum's Alistair Willis.
"These stories and the collection are fascinating, and it is wonderful that Amgueddfa Cymru has the opportunity to display them."
Hughes said he had been to the beach more than 1,000 times and spent thousands of hours searching for the shipwreck's treasure.
He said the vast majority of his visits to the beach had ended up with him finding nothing, adding that it was lucky he had a "high tolerance to disappointment" and the "thrill of searching just kept me going".
