seen a lot of these in flea markets and book dealers for £3 and £4 and upwards.  Vinted no good as no ISBN.  Might go to a good bookseller near me unless someone knows of a better way.  Rather not go down the ebay or abebooks route unless someone says it's a really good idea

you probably won;t get much with a bookseller / dealer - they have to make a profit and the margin there would be small. try a flea market? or ebay?

You've answered your own question - either get a stall in an antique market, or approach someone who has one and see what they'll give you for them. If they're asking £3-£4, I'd expect they'll want to pay no more than a pound each unless you have something very special.
