How much are the mini cards of honus wagner,sherry "magie", lewis (boston-nl),and eddie plank worth?

Their not any name brand nor do they have a specific year on which they were made. On the back of each card it has their name, value, and it says 1910 tobacoo card. all three descriptions are on the top of the card in a red box. The middle has a slite discription of the orginal cards history. all four cards are in fair condition.
