To be honest Mark, (and as Joe said), £250 value is way too high IMO.
Proof of pudding is that your Little Oscar is still in my collection (as is your Nat Hall), at a price we were both happy with.....if I had sold the bugger for £200 you would certainly be justified in worrying about losing any coin on it.
I definately wasn't willing to pay any higher, and I bet a pound to a penny you had no other higher offers for it when you listed it for sale on here.
In which case, perhaps I paid too much?
A record is only worth what the highest bidder is willing to pay at the end of the day.
Has anyone actually bought or sold Little Oscar above the £150 mark?
I personally doubt it, but I have been wrong before....
Only the once mind......
