The 1954 $20 (Devil's Face, Coyne-Towers, Asterisk Replacement) Bank of Canada Note was printed for the Bank of Canada with a recorded printage of 7,200 notes — the 8th-lowest of the 25 notes of the type in the 1954 devil's face banknote series, and less than half of one percent of the 506,721,986 devil's face notes printed before the fix.
A full collector's note for this issue — survival, strike character, and what to check before buying — is on the writing schedule; the figures above are the permanent record.
