An older lady this weekend gave me some things, and in the box, was 32 cut outs from cereal boxes. Most of them have dates and they are 1963, they are from Kelloggs. They all have biographies of famous people throughout history. A few of them are: John Slaughter, Osceola, Amerigo Vespucci, and Christopher Columbus. All of them are just the pictures and words, it seems they were cut out of a back of a cereal box. The are in overall good condition for the age. They all do have a hole punch on the top left hand corner, they must have been at one point kept on a ring. Are these worth anything? How should I go about checking out the value?
