Educated guesses mate.
1) Second Coming artwork promotional large poster-sized board, covered by a thin acetate sheet with words:
STONE ROSES
This depends on the what someone who wants it would pay..There's no sort of value for items like this..
I'd say lowest £10 highest £20.
All depends.
2) Original One Love 7", complete with postcard. Mint.
STONE ROSES One Love -- (UK 7" + limited postcard, p/s ORE 17) 3.99
( Opal Music )
3) Love Like a Fountain 12" white label, mint condition.
Lowest £10 Highest £20.
4) Golden Greats Promo CD, mint condition.
I paid 12 quid for this.
( Embossed one )
5) signed Love Like A Fountain CD single, excellent condition.
Mines signed too..Paid a fiver.
6) Signed (and certified) Can't See Me CD single. Mint.
Lowest £5 Highest £15.
Hope that helps mate, and are really only rough guidelines..
People will pay what they want for them if they want them enough.
