How much did the first compass cost?

Answer 1

The first compasses, developed during the Han Dynasty in China around the 2nd century BCE, were primarily made from magnetic materials and were relatively inexpensive compared to their value in navigation. However, specific cost details from that era are not well-documented. Over time, as compasses became more refined and widely used, their prices varied based on materials and craftsmanship. Today, the historical cost is difficult to ascertain in modern terms.
