This is a functional quadrant coin which you can actually use to locate your latitude. The quadrant was quite simple in its early days and had many functions added after it was refined by surveyors and navigators. The simple method is for you line up one straight side and aim it at the pole star Polaris. Then the weighted plumb string dangling down intercepting the arc would indicate the degree of latitude. How to use it: 1. Locate the North Star, Polaris. You can also use it in the Southern Hemisphere if you know how to triangulate the Southern Cross and Centaurus constellations to locate the southern axis point. 2. Hold the quadrant vertical and ensure there is nothing obstructing the weighted string. The weighted string must hang freely, but still lightly brush up against the degree scale. 3. Hold the coin straight out from your face; and line up the two triangle points on the edge of the coin with the North Star. Taking a sight with the Quadrant Geocoin 4. Once you have a good fix on Polaris, carefully pinch the lower end of the string onto the quadrant to prevent it from moving. Be careful to not pinch the string in a way that covers the degree scale. 5. Turn the coin around and look on the degree scale to see where the string crosses it. You now have your approximate latitude.
