I have a complete set of 1960 Collier's Encyclopedia including the bibliography and index. How much do you think the set is worth?

I have what appears to be a first edition of Collier's New Encyclopedia, 1902, in 16 volumes. I can't find any others for sale on the usual sites (ABE, eBay, Amazon, etc.). Any ideas for a value?
I also have an Americanized Encyclopaedia Britannica, 1899, complete in 10 volumes.
