A promotional system includes an envelope or sleeve, an article of currency and a label removably attached to the article of currency. The envelope or sleeve has a length less than that of the currency and a through opening in one face so that, when the article of currency is received within the envelope or sleeve, the portrait portion of the article of currency will register with the opening and part of the currency will project beyond the end of the envelope or sleeve. Either or both of the label and envelope or sleeve carries machine-readable indicia. Reading and display means are provided whereby the envelope or sleeve and/or the label may be read and a display actuated upon insertion into the reading means. An alternative embodiment includes a second opening in the one face of the envelope or sleeve positioned so as to overlie at least a portion of the inserted label. A further alternative embodiment includes just the article of currency, the indicia-bearing label and the reading and display means.
