In the 16th century, large coin transactions in India were a complex affair which was managed by merchants' trade organizations. These organizations provided escort services and transported gold through various trade channels which were concealed among their regular supplies. They were heavily supported by the soldiers of the kingdoms involved.
When Aditya was awarded the new contracts, tokens were issued to merchants alongside gold from the treasuries of allied kingdoms. These tokens were meant to facilitate the transport of gold under the protection of soldiers of related kingdoms.
