Royal Dux Bohemia: Duxer Porzellanmanufaktur, or Dux Porcelain Manufactory, was started in 1860 by Eduard Eichler in what was then Duchov, Bohemia. The high quality pottery and porcelain figures produced there are now generally referred to by the abbreviated name, "Royal Dux."

Ownership of the business changed frequently over the last 150 years. Bohemia became part of Czechoslovakia which was in turn controlled first by Germany then the Soviet Union. In 1990, even the national name was changed to Czech Republic.

The problem facing collectors is that many original 19th century molds have remained in production throughout the company's 150 year history. With vintage 19th century Royal Dux selling for up to several thousand dollars, modern pieces are often offered, either deliberately or through ignorance, as much older than they really are. In this article, we'll be looking at genuine marks found on authentic Royal Dux as well as typical forged marks you might find in the market.
