It won't make a significant difference to the overall price.
Unfortunately the market is right down at the moment and inserts from releases such as champions (20 or 25,000 boxes) don't fetch much, especially just a few random bits.
Double Trouble were 1:216 (1 per 6 boxes) and when they first came out they may have fetched $50+ but truth be told they are an non numbered insert that are very easy to acquire if needed
The folder and commons and parallels are worth very little like David mentioned
The sketches and foil signatures might fetch $2-$3 each at auction, Gems $4 - $5 each (Slater MIGHT jump a dollar or two further) and the Double Trouble might go for $20-$30 at auction.
Good luck with your sale.
