The Guldengroschen or Guldiner was a large silver coin originally minted in Tirol in 1486, but which was introduced into the Duchy of Saxony in 1500.
The name "Guldengroschen" came from the fact that it has an equivalent denomination value in silver relative to that of the goldgulden (60 kreuzer). In the latter years of the 1470s and early years of the 1480s Sigismund of Austria issued decrees that reformed the poor state of his region´s coinage by improving the silver fineness back to a level not seen in centuries (.937 pure) and created denominations larger than the ubiquitous, but fairly low valued Groschen of 4 to 6 Kreuzer that were in use.
