Mongoose banner, Whats it worth?

[Nicfred]

Didn't really want to sell this but i need some money to buy a pick up to pull my trailer, so may sell this and some other stuff, but no idea what it's worth, i hate to say it but i guess the dreaded   ebay is the best place to get the real value? Mongoose original paper banner, been in my cupboard for years  







Also this GT RTS
Brought new back in i think, towards the end of the 90's  the frame cracked and was out of warranty, i spoke to someone i know who worked for a GT sponsored rider   and they sorted me out with a brand new frame  built it up and i have not used it since then
