Hello!
I have book to sell, it looks rare but I don't know enough about books to understand its value (I don't normally sell books, this is my own).

It's Sylvia Plath's Ariel, 1st edition, second impression, 1965, Faber and Faber.
I've done quite a bit of research and found that 1st editions are valuable, but I don't understand if being a second impression would make it almost worthless (obviously it would depend on its condition as well).

Any advice is greatly appreciated.
Thank you
