1 Cent - Sloan's Supermarket Sloan, New York

Sloan's Supermarkets operated a chain of grocery stores primarily in New York City and Westchester County from the mid-twentieth century, and trading stamps or store-issued scrip of this kind were a common promotional tool during the postwar retail wars — supermarkets competed aggressively on price and loyalty incentives when margins were razor thin. Whether this cent denomination functioned as redemption scrip, a cash-off coupon, or part of a trading stamp program isn't always clear-cut; the distinction mattered legally in some states, which regulated scrip issuance differently from promotional coupons.
