The Canadian one-hundred-dollar note is one of five banknotes of the Canadian dollar. It is the highest-valued and least-circulated of the notes since the $1000 note was gradually removed from circulation starting in 2000. Each note in the 1988 series was sprinkled with special green ink dots that glow when exposed to ultraviolet light. The ink can be scraped off, so worn notes tend to have fewer if any, glowing dots. These were replaced with more permanent ultraviolet-detected threads in the new notes, as well as an ink imprint of the coat of arms.
