hong kong two-dollar coin





















































the two dollar coin is the third-highest denomination coin of the hong kong dollar. since its introduction in 1976, it is one of two circulating coins to not be round (the twenty cent coin is also not round). the two dollar coin is a dodecagonal scallop in shape, and made of cupro-nickel.





















































it was issued in 1975, and thus became the highest denomination coin until the five dollar coin was introduced the next year. the coin was a new denomination to the hong kong monetary system, as suggested by the coinage review committee.
