In 2007, 2016, 2017 and 2018, the
Royal Canadian Mint (
RCM) issued $8 non-circulating legal tender (NCLT) collector coins with a Chinese theme and a square hole in their center.
From the
RCM's web site regarding the 2007 issue: "This unique coin was inspired by the square-holed coins that came into use in China after 523 B.C. Many believe its round shape symbolized heaven while the square represented earth. These coins were cast from bronze and the holes enabled them to be strung on a cord — 1,000 coins forming the main purchasing unit in use at the time."
Here's my 2007 coin.

I posted about the original 2007 coin here:
