Hi there,
A full 2010 prize set? Lucky!
I've got one of them myself, most of it manually put together.
My estimate would be around $480 for the full set if you were to sell it. A bit extra if you've got the folder and certificate that comes with it.
It's the last of the traditional prize sets, however unlike the previous few years, it lacks that special Premiership set for the premiers of the previous season (Those were moved to the gold set). It's still a rare enough set, got some very lovely cards.
Hope this helps.
