I have the certificate. Ball park value?Without a certificate around £150 I'd of thought. With a cert then a LOT more.
whatever the punter wants to pay and depends on who is bidding for it on eblag. it may not fetch what its true value is
I'd of thought a grade 0 plate with a cert would be four figures to buy new. You probably wouldn't get anything near trying to sell on eBay as people aren't looking for top notch gear.
Is it a Granite or Cast?
