From tropical Clownfish to Humpback whales, we have hundreds of legal tender sealife coins that represent all manner of marine life. One of the premier series of legal tender sealife coins was issued by the island nation of Palau beginning in 1992 with the first of their Marine Life Protection Series. These coins have become a collector classic, featuring both examples of sea life on the reverse as well as mermaids on the obverse. These coins have been struck in copper-nickel, silver and gold, with the latter two becoming exceedingly rare to find. Other countries, too numerous to list here have also issued sealife coins, many of which can be found on this website.
