MGM Grand 1973-1986 There are 5 or 6 varities, allfeature the same front with different images/promotions on the reverse. Late 70's early 80's. $1 to $3

Peppermill 1982-1989 This ones a little easier to date as the Western Village in Mesquite opened in 1987 so clearly from the '87 to '89 period. $1 to $3

Holiday Casino 1973-1992 I would guess from the 80's very common, in used condition, $1

Hotel Last Frontier 1942-1955 This should be a feature matchbook i.e. printing on the sticks. If so and is in full unused condition I would say $10-$20 or more, certainly an early piece of strip history. Last Frontier was located across the strip from the Desert Inn and was re-named the New Frontier in 1955, nice find, Eric
