Compass Rose Geocoin 2011 - Dawn to Dusk

The 2011 Compass Rose Geocoin® is about the critical importance of the sun and navigation. Navigation by the sun was practically second nature a thousand years ago, even though it was not as accurate without special tools as today's methods. It was very important to know where the sun tracked across the sky and exactly where it would rise and set depending on the season. Since the 1700s, knowing the sun's declination was imperative to calculate longitude. Knowing how to gain longitude was very important to calculate accurate navigation and map making.

The compass rose sun design on the 2011 Compass Rose Geocoin was derived from a map made in 1613. The map covers half of the world on the Atlantic side. Normally, maps containing a great level of artistic detail were not accurate and made only for sale to the general public as display pieces. Ship's captains knew better than to use these kinds of maps; however, this map was not only artistic but also informative.
