Hard to put a value without seeing how it cleans up, There appears to be some pitting in the bottom cooking surface of the pan, That will affect value, Some of the basting drippers also appear to show some deterioration which again will affect the value.
What does the writing in the basting drippers say, It looks like a number 4 and the word PATENTED.
Clean that bad boy up and repost some pics to this site so they will be permanent
