I have these Italian carts and was wondering if anyone could tell me how much you think they're worth? None of them have boxes, but some do have instructions.

They are:
Kirby's Adventure ( + instructions)
Lolo 3 ( + instructions)
Maniac Mansion
Nintendo World Cup
Super Mario Bros / Duck Hunt
Super Mario Bros 2 (French cart)
Super Mario Bros 3
Tecmo World Wrestling
Tiny Toon Adventures
Trolls in Crazy Land

And these 2 UK carts:
Solstice ( + Instructions)
Swords and Serpents

Where do you think would be the best place for me to sell them? Ideally I'd like to sell them only within the UK, as that's where I am, and am not too trustworthy of overseas shipping.

Any help is greatly appreciated  :)

Edit: Anyone is more than welcome to make offers.

£2-£3 each, a bit more for Trolls in Crazy Land. Best place to sell them is probably uk ebay except for the SMB2.

As it is French SMB2 wont work on a UK NES.

Thanks for the info. I've just put Trolls on ebay here. Hopefully it does well.  :)

Also, I tried playing SMB2 on my PAL NES and it worked fine.
