Every devil's face hundred came out of one prefix block, A/J, and the block was split between the two signature eras: 1,677,884 notes signed Coyne-Towers, then 679,644 signed Beattie-Coyne before the modified face took the denomination over in 1956. That makes this the smallest regular printage of the type after the $1,000, on a note that was actually used as money.
The figure is a clean lesson in how this series works. Nothing about the hundred was rare by design; it simply had the shorter half of a shared prefix when the clock ran out on the devil. The deadline, not the denomination, set the number.
High face value kept survival rates decent, so this is a rarity you can genuinely shop for. The usual trap is the signature: the Coyne-Towers hundred is two and a half times more common and looks identical at a glance.
