large Star Wars Millenium Falcon value?

Hi all,

I've found my old Millenium Falcon model when clearing out the attic, and wondering if it's worth anything. It's unboxed, assembled and painted...

I bought it around 1998 and had no idea what it is until searching around online - I now think it is probably a 1/68 ERTL ROTJ Falcon model as per this Ebay link:

Can anyone confirm whether that's correct and if that Ebay value of £30 is about right?

See attached for some pics.

Thanks!
Ian

I'd imagine the unbuilt one would be more desirable but that didn't sell at £30
