Value

I just recently purchased an Emmett Kelly Sr.amimate musical collector doll with all of the authentic accessories, which includes the wind up musical , Emmett Kelly Sr. doll, an authentic park bench, Emmetts nap sack , his hat, and has an certificate of authenticity. Includes the box it came in which is in perfect shape. The item No. is 255-7 "on the road".
His head moves during the music when one winds it up. It has to be a very valued piece, as I have never come upon one. Could someone give me an idea of its real value, it is perfect, and the approx date that it was made. Its going into my Emmett Kelly collection, as I Klown for the Shriners.
