As reported at HuffPo (and many other venues):
VIENNA -- A man turning dirt in his back yard stumbled onto buried treasure – hundreds of pieces of centuries-old jewelry and other precious objects that Austrian authorities described Friday as a fairy-tale find.
Austria's department in charge of national antiquities said the trove consists of more than 200 rings, brooches, ornate belt buckles, gold-plated silver plates and other pieces or fragments, many encrusted with pearls, fossilized coral and other ornaments. It says the objects are about 650 years old and are being evaluated for their provenance and worth...
While he found the ornaments in 2007, Andreas K. did not report it to the memorials office until after rediscovering the dirt-encrusted objects in a basement box while packing up after selling his house two years ago, said Profil. The soil had dried and some had fallen off, revealing precious metal and jewels underneath.
