PALAU. 200 Dollars, 2000. NGC PROOF-68 Ultra Cameo. Fr-Unlisted; KM-Unlisted (though cf. KM-51 for similar issue in silver). A <strong>VERY RARE </strong>and interesting issue type stresses the importance of the environment through the phrase "our world, our future," along with a colorized map of the world. Dazzling and highly appealing.
