Star Trek fans are “Spocking” their money to honor Leonard Nimoy. The phenomenon of “spocking fives”, which involves etching the beloved Vulcan’s profile over Canada’s seventh prime minister Sir Wilfrid Laurier on the five-dollar banknote, has existed in Canada for years, but Nimoy’s passing has made it even more popular.
According to the Bank of Canada it’s not illegal to do this but:
“…However, there are important reasons why it should not be done. Writing on a bank note may interfere with the security features and reduces its lifespan. Markings on a note may also prevent it from being accepted in a transaction. Furthermore, the Bank of Canada feels that writing and markings on bank notes are inappropriate as they are a symbol of our country and a source of national pride.”
