How much is my set worth?

[ceder]

I have a pokemon southern island set but I only have 15 of the 18 cards and I have the binder I wanted to ask how much its worth and if its worth something where can I sell it and I live in the netherlands so I use euros.

It's worth the combined value of the individual cards and the binder. If you don't have the whole set, it's not going to be worth nearly as much as the complete set is. Which cards from the set do you have? And which language is it in?
