One old money story is about the Vanderbilt family. They were among the richest in America. They built grand mansions and had a lavish lifestyle. Their wealth came from shipping and railroads.
There was the story of the Fugger family in Germany. They were wealthy merchants in the 15th and 16th centuries. They amassed great wealth through trade, especially in textiles and mining. Their financial power even allowed them to loan money to kings and emperors.
Well, old comics from the Golden Age of Comics, such as 'Action Comics #1' featuring the first appearance of Superman, or 'Detective Comics #27' with the debut of Batman, are highly sought-after and can be worth a fortune. Also, comics with unique storylines or limited print runs tend to have higher value.
