Looking to sell my Winx Club doll's, but I don't know what price range they are in? Options

[Emi]

When I was younger I purchased many Winx Club doll's. I have First Wave/First Season Bloom, Stella, Musa, Flora, Tecna & Icy (they were produced by Mattel and light up), also have Layla/Aisha in her fairy form, she lights up at the back too, she came with her Pixie and Singsational Layla/Aisha.

I have all their accesories and clothing & they are in pretty good condition. I am -thinking- of selling them, so I would like an idea of how much I should price them at? They only ones I am no 100% sure on selling are Icy & Layla in her fairy outfit.

I also have the Alfea Winx school, I don't know whether I am selling that yet, but what would you price that at?

Thank you!
