SINGAPORE. 1/4 Ounce Gold (3 US Trade Dollars), 2000-SM. Singapore Mint. NGC PROOF-70.A RARE and attractive mint medal, struck on scalloped planchet with a Year-of-the-Dragon theme, the obverse displaying two dragon boats while the reverse shows a facing dragon similarly styled to the early Chinese dollars. The first we have seen of the type and particularly interested due to its notation as a trade piece with a value of $3 USD.
