It is some type of hard glossy plastic.It is not bakelite and I am pretty sure it is not celluloid.It's not real heavy,but not too light weight either. I am guessing 50's era? It measures 3.5" from tail to nose end x 1-3/4" high.There are no markings.
I am not very experienced with jewelry.I have done pretty well with pieces that were marked,but I am left with two shoe boxes filled with mostly unmarked jewelry pieces and many I cannot find anything similar with research.This is the first piece of many that I hope no one minds me posting for any help possible. Please let me know if any additional pics are needed.Thanks so much!
Thank you for your help I greatly appreciate it! 
I did test it. I'm usually 99% correct with knowing if something is Bakelite,but this pin had me getting my tube of simichrome out. It feels and sounds like bakelite,but tested negative.Not even a slight change in color.No other tests gave a positive either. But I thought of something last night that I haven't come across in a long time with a bakelite piece.I'm pretty sure it is covered with a clear coating of something. There is no place to get through the coating to do a pin test that it would not leave a mark on it.The coating is throughout the entire pin without even a scratch on it.
I think I am going to do a bit more research on testing coated bakelite to see if I can find a way to see if that could be the mystery with this pin. Thanks again!
