If I was buying one Ham, knowing that Toni probably has a garage full I wouldn't pay more than £150 for one. Regardless of AFA prices or the fact that he sells them for quite a bit of cash on his site.
As for the Vintage market, it's always been WEIRD and depends on too many factors.
Although I honestly believe market value can't always be determined by these random anomalies or funny trends, with a trend there is always going to be a point where the market is saturated and prices come down (Like Andy mentioned), so if you were caught up in it and grabbed them at their highest price you will inevitably have lost money whereas others who got in early or waited for it to pass will buy things at more reasonable prices.
As for AFA graded figures going for X amount one week and double or triple the next - That's just down to people bidding that either have had one too many or have no idea :lol:
You know yourself that the REAL price of a loose mint VCJ (that would probably grade 85) is a lot less than £530 and if you were to grade all of yours at 85 you probably couldn't sell them all for £530 on ebay because people would see 4-5 AFA 85 Jawas listed and think - wow not so rare after all? so it can only be a random uneducated buyer or someone who has been at the drink lol!
Personally I understand paying through the nose for quality IF it's super hard to find the item in good condition period. When you know there are loads out there in solid C9 it kinda defeats the point of paying more for something just because it looks nice. Reminds me of the Zebra from Madagascar when he meets all the other Zebras and realises he isn't so special after all :lol:
