Mr Pearce said on the first page of the book there was a £2 pencil mark, which was the cost the library sold it for when it was checked out.
He said the misspelling of philosopher’s on the back of the copy was among the things that identified it as a first edition.
“It is missing the ‘o’ at the end,” he said.
Other differences found in first editions include “inside the first couple of pages you will notice the title line has the numbers extending from 10 down to one”.
Mr Pearce said another copy, in a similar condition, sold in November for £42,000 including the fees.
“There are still a few out there,” he added.
“I believe they are the most expensive contemporary first edition you can get now.”
