Under the ground is where treasures are usually hidden so they are usually forgotten — only to be discovered later by some lucky diggers. 

In Neuville-sur-Saône, a suburb of Lyon, France, a resident digging up his garden to put in a swimming pool in May stumbled on plastic bags containing five gold bars and coins, local reports said. 

The man reported the find on his property to local authorities to legally claim ownership of it in accordance with regulations. Having been found in a non-archaeological site, authorities ruled the finder could keep the gold worth $800,000, according to Agence France-Presse. 

However, a lawyer told The Times that the heirs of the deceased owner of the gold were entitled to keep it or, in their absence, the state should have it. 

Meanwhile, a rare “treasure” was found above ground, in the attic of a house in San Francisco, California, USA, last year. 

Three old brothers were sorting out the belongings of their late mother when they discovered their uncle’s collection of vintage comic books that their mom had kept, ABC News reported. 

The comic books bought during the Great Depression and World War II included the maiden issue of “Superman” printed by DC Comics in 1939. The rare copy reprinted the earliest stories of the superhero published in Action Comics, whose first issue printed in 1938 introduced the Man of Steel. 

In an auction last month, the 64-page Superman No. 1 was sold to an anonymous bidder for $9.12 million to become the most expensive comic book ever, surpassing the $6 million fetched by Action Comics No. 1, where the iconic flying superhero first appeared.
