My own renovation projects have never proved this successful.

Cash in the attic! $1million in gold coins rains down from the rafters as workers renovate vineyard building in Champagne
A team of builders renovating a vineyard facility in France were stunned when U.S. gold coins worth $1million rained down on them from the rafters.

The treasure trove of 497 coins was hidden in the attic of an old building in the rural village of Les Riceys in the country's famed Champagne region.

The pieces, which have a face value of $20 each, were minted between 1851 and 1928 and are the equivalent of 17 kilograms of gold.

They are today worth about $980,000 (622,000).
