Coupon

Coupon (Fr. couper, to cut), that part of a bond, stock certificate, or security which is detachable from the main portion, and whose detachment only affects the main instrument so far as the coupon itself is concerned. Modern travel has made most of us acquainted with the compound railway ticket, whose coupons are detached at various stages of a journey, while the cover or main part is retained till the last.stage. Theatre tickets sometimes have a coupon, which the ticket holder retains after giving the other part up.
