I found this info on a site
"Additionally, 11 of the figurines (Aaron, Banks, Berra, Fox, Mantle, Mathews, Mays, Minor Leaguer with white base, Musial, Ruth and Spahn) were made with magnets attached to the bottom of each foot which were then accompanied by a small black metal plate that would serve as the base for which the magnets would adhere. The presence of a small hole was intended to allow a nail or screw to be used to then fasten the plate to another surface."
^^^Could this be your statues....maybe they were made to be made into other things like lamps, mantle clocks, etc
