It appears they could be from the 1923 W572 set. Here is a short discription of the set. This information is from the 2009 Standard Catalog of Baseball Cards

These cards, designated as W572 by the American Card Catalog, measure 1-5/16" x 2-1/2" and are blank-backed. Fronts feature black-and-white or sepia player photos. The
set is closely related to the popular E120 American Caramel set issued in 1922 and, with the exception of Ty Cobb, it uses the same photos. The cards were originally issued as strips of 10, with baseball players and boxers often mixed. They are found on either a white, slick stock or a dark, coarser cardboard. The player’s name on the front of the cards appears in script. All cards have on front a copyright symbol and one of several alphabetical combinations indicating the source of the photo.
