Two technologies of making coins beautiful have come together on this issue from Palau, a small island country in the Pacific Ocean north of Australia and East of The Philippines.
First, the coin is struck in high relief, allowing for more detail in its design. This process is more expensive than lower relief strikes because the dies wear out faster, requiring much more force in each strike. The coins are also struck more than once to bring out the full detail in the design.
This coin is also selectively gold plated, which is actually a pretty complicated process. The gold color of the border around the horse accentuates the horse design and separates the horse nicely as the chief focal point in the design.
