Builders have stumbled upon a treasure trove of 200-year-old coins worth nearly half a million pounds.

The 10,000 coins were discovered during renovation work in the historic city of Krakow in Poland.

Made of copper and minted in the time of the 18th century Polish king Stanislaw Poniatowski II, the rare copper coins had been stashed in the basement.

The coins were also hidden inside linen bags, which have since rotted away, when they were placed in the tenement building.

Copper coins from that period can be worth up to £40 each and experts estimate that the total value could therefore be as much as £400,000.

The coins have now been handed over to the Krakow Archaeological Museum, which will try to solve the mystery of how they got there and also preserve them.
