Why is "Blacksmith token" trending?

Wikipedia Overview

Blacksmith tokens are a form of evasion currency that was in circulation primarily in Lower Canada and Upper Canada along with neighboring areas, such as the northern parts of New York and New England in the mid-1820 to 1830s. They were not, strictly speaking counterfeits, but instead skirted around the laws of the time by being similar to officially circulating coinage, but bearing different legends, or bearing no legends or dates at all, so it could not be claimed that they were truly imitating circulating coinage fully. The tokens were designed to resemble worn examples of English or Irish copper coinage, most often with a crude profile of either George II or George III in profile on the obverse and an image of Britannia or an Irish harp on the reverse. They were typically underweight when compared to officially sanctioned halfpenny coinage, but were accepted along with many other unofficially issued tokens due to a lack of sufficient small denomination coinage in circulation at the time.
