Whats it worth??

[Kliro]

Hey, I was just wondering how I'd be able to find out how much this is worth.

I've got a first edition of harry potter and the goblet of fire, signed by JK Rowling.

Not in perfect condition as its been read a couple of times, but still reasonable and with cover etc.

TIA

Depending on condition it could be worth a bit
