Speculation is that it may be Nazi gold but this is disputed.
A teenager has made an unexpected find while swimming in a lake in the German Alps: a 500-gram (17.6-ounce) bar of gold. Police said Wednesday that they are still trying to figure out where the bar comes from and how it got into the Koenigssee lake, a popular tourist destination near Berchtesgaden on the border with Austria.
You can see that some marks have been scraped off which may make it more difficult to track down where it came from. How it got into the lake may never be known. Police did not find additional pieces in the lake but you can bet lots of others will go looking.
A person with a metal detector found a stash of Nazi gold, in coins, buried under a tree near the northern town of Lueneburg, Germany last October. The news was released last month. Troves of Nazi gold are the subject of many conspiracies and speculation.
At least it wasn’t a gold ring with strange writing on it…
