Need help determing a value of an Emmett Kelly Jr Animal Clown Stuffed Animal

I currently have an Emmett Kelly Jr Animal Clown Stuffed Animal that I have had for over 20 years. It was made by Luigi Amani & Co. It is 20" tall and has number of EC-1. It is in excellent condition and I still have the box. I am trying to find out a value of the stuffed animal of help in determining the value. Please let me know if you could be of any help. Thank you.
