It all depends on how many are produced and of course demand for them. The Mambo Sandman and the Holden Effigy released by Classic's a few years ago can not be bought now for less than $550. I have the Biante Indy Orange HG and you won't get one of these for less than $350.
production numbers range from 1200 up to 3500 and generally don't sell out all that quickly unless they are special release like those listed above. I have never pre-ordered and have never missed out on cars I want.
If they sell reasonably well the Sandmans will be further produced in different colours so I doubt they will increase in value very much unless the release numbers are small.
