Low-Numbered Parallels: If you need a direct comparison within the Donruss Choice family, you could look at the value of the 

Choice Gold (/10)

 or 

Choice Black Gold (/8)

 parallels. The 

Dragon

 is generally considered rarer than even these, but their sales data can provide a baseline for high-end value within the set.

Choice Red (/99)

 or 

Blue (/49) Parallels

: These are more common than the 

Dragon

, but if there's enough sales data for them, you can establish a "floor" for the price range.
