Each brooch/pin has a silver metal pin (there are no markings to say what type of metal it is). There are no maker marks on either pin, but I was able to determine the maker from pictures of the pins. The bird brooch/pin measures 1 1/4 wide and deep. The hedgehog brooch/pin measures 1 3/8" wide and 1 1/4" deep.
These pins have some wear and age to them. There are small imperfections on them on the front and back (see photos). There is a glaze pop on the back of the hedgehog pin (see photos).
