Guild President Bernard:
Honestly, after you came to visit me, I was intrigued by your words and did some research. With help from union members I found out where the coins are often discovered.
Lakin and the vanor silenos in the south of Aden, and Timak orcs of northern Oren have these coins.
The coins are also often discovered in the Bandit Stronghold in Oren, the Cemetery of Kings in Aden and Dragon Valley.
