Two people in Poland have claimed to have found an abandoned Nazi train from World War II, which they say is full of 300 tons of gold, precious stones and weapons.

The two, one from Poland and the other from Germany, have reported their find to the Walbrzych District Council in southwest Poland, and have offered to give the location of the train - if they are promised a 10% cut of the looted treasure's value.

Given that 300 tons of gold would be worth $1.09 billion today, that 10% would equal over $100 million.

According to the two people, who asked to remain anonymous, the train is 150 meters long and located somewhere in the environs of Ksiaz castle, 77 kilometers (nearly 50 miles) southeast of the town of Wroclaw.

It would appear the train is one of many that the Nazis used to bring goods stolen from Jews and other victims in eastern Europe back to Berlin in Germany. Near the end of the war as the genocidal Nazi regime crumbled, the train apparently was deserted as Soviet soldiers pushed back Adolf Hitler's troops.

Marika Tokarska, an official at the Walbrzych District Council, told CNBC that the council was indeed contacted by a law firm working for the two people who made the discovery.

"We know that is a military train with guns on it. We can suppose that inside could be also other weapons or even dangerous materials. Even methane gas (could be) inside of the tunnels," she said. "We need to take care about people's safety in this area. That way we couldn't ignore this information."

According to her, the offer to divulge the train's location in return for a 10% cut is being taken "very seriously."
