Mintage of only 2,500 coins! The Color Medium Application Technique makes an amazing visual effect on these .925 silver coins. Depending on the beholders perspective, a part of the colors change. The dazzling and fascinating play of colors of the feathers is brought by a light refraction in the air chambers and not in the color pigments. On the obverse are the coat of arms of Palau and $5 denomination. This coin comes to you in the original capsule and includes a Certificate of Authenticity from the Republic of Palau. This issue is incredibly hard to find in the United States!
