Encyclopedia Set Value?

I am looking for the possible value of a complete 10 volume set of The University Encyclopedia of Twentieth Century Knowledge with a 1902 copyright date. This set is in very good condition with only some loose binding; spines are strong for their age. The editor of this set is Henry M. MacCracken, D.D., LL.D, then Chancellor of New York University. It was published in New York by The Co-operative Publication Society and copyrighted by P. F. Collier and Son
