How can I find out the value of a fur coat bought second hand?

Today i bought a real fur coat at a costume sell from a dinner theatre. Despite it being real i got it for an extreme bargin and would like to know the original price of it. Looking into it the label sys Arctic Fur Co. Cinncinati, and then on the inside towards the bottom the initials "FMC" are sown into it. Im not sure how old it is they had things there anywhere from 1930's up. I looked up Arctic Fur Co. but really didnt find anything on it. Any advice?
