These are diecast pieces. There are two motorcycles (One natural lead color the other slightly pinkish-red) and a bicycle charm or necklace attachment which is bass-colored. They are double-sided. The two motorcycles' stand up and are about 1 1/4" x 1 1/8". the bicycle is about 1 1/4" x 3/4". I'm not sure how old they are although they were part of an Indian Motorcycle collection I purchased with most pieces being from 1913 on up to the 1940's.
