Help required

So I have recently been left some kites, 11 in total and a big bag to hold them, the person who left them to me was an enthuisiast and in most hobbies bought quality stuff. I know a few of these are probably cheapo copies, what Id like is more information if possible regarding any of them. General plan is keep a couple of the cheap ones to fly in his memory occasionally and then if any are worth any money to sell to to put towards a bench to put in his favourite place.

Aby help would be greatly appreciated
