Mining areas and minting chambers in medieval Hungary.
“There is a generally-accepted estimate that in the 14th century, Hungary’s mines produced at least one third of the known world’s gold output, and 80-90% of Europe’s!”
The source for this claim is Zoltán Batizi, “Mining in Medieval Hungary” in The Economy of Medieval Hungary (Brill, 2018), page 174.
The author also provides a map of mining areas in medieval Hungary!
He adds that “The crown was concerned with silver as well as gold: several gold-producing settlements were granted charters as towns, and the freedoms of existing towns were confirmed. Hungary’s silver production had a distinguished place in Europe, too, second only to Bohemia. Some 2500 kilograms of gold and 10,000 kilograms of silver were produced each year.”
