Frappé au coin du bon sens

Meaning: Manifestly sensible; bearing the stamp of sound judgment.

Literally: Struck with the die of good sense

Example: “Sa proposition de décaler les horaires est frappée au coin du bon sens.” — Her proposal to stagger the hours is plain common sense.

Origin: The coin here is the engraved die used to strike coinage, not a corner. A coin bearing the official mark was guaranteed genuine, so an argument struck with the die of good sense carries the same warrant.
