I want to know the answer to the following question:
What is the modern name for St. Joachim's Valley?
All the background I'm provided with is that "Alternatively, thaler is said to come from the German coin Guldengroschen ("great guilder", being of silver but equal in value to a gold guilder), minted from the silver from Joachimsthal.". Is that enough to answer the question?
Answer: no
