Shakespeare

[joker]

Hello everyone am new here. I bought 2 books on shakespeare at a yardsale and am hoping someone can help me with a little information. There are two volumes of a three volume set. The Complete works of Shakespeare, Charles Knight, I think I have pinpointed the date around 1861. The bindings are in bad shape but the pages are in great shape for their age. Has steel engravings inside. I would love to know what the value on these are if any. Thanks for any and all help.
