You may not even realise it, the fact you own a first edition. Lurking on bookshelves and hiding in cupboards, first edition books look typically like any other, its only within the sleeve or first few pages that you can discover the true origins of the book. First prints are usually worth a few quit more than the reprints, the older the more the difference. Some first edition books have been known to go at auction for millions of pounds.
