Selling Victor Books for Boys Anuuals 1966-1970 HELP!

[LilyLoo]

How would i find out if these are worth any money? I have six in total 1966, 68, 69, 70 and two 'The commandoes at Singapore' and 'The Commandoes at St Nazaire'. Where would i be able to sell them ?
Thanks

Having a look on Ebay (completed listings) is always worthwhile to see what people are paying.

You could also try some of the secondhand sites like www.abebooks.com but remember they are retail prices, not what you'd get if you sold to a bookseller.
