Ditto on the approx. valuation, depending on which venue though and timing I'd say though $600-$1200. I've seen some nice covers on ComicLink the last few OA auctions go for that range that I expected to go on the high end actually go for lower in the cover-tier price range. If it was more of a full-body Carnage shot it'd hit $1k easily, but since it's mainly a torso it'd have more variable in the pricing. If it was one of the Del Mundo covers it'd also hit the $1k price easily since those were a draw. Perkins is a solid artist and has longevity in the field, but not really a big name recognition as others. Still a nice cover that should sell nicely.
