I believe these are old Cracker Jack prizes, but they could have been from a gumball machine. The chick hatching from an egg, and the stork with baby stork on his back are made of celluloid plastic, and would be from the 1920s-30s. The 2 identical elephant charms are made of an early plastic. My guess is that they are from the 1940s-50s. I'm including a newer, silver color, animal charm because it was with the group when purchased.
