That's a large hood, have a look as this link to see a side by side comparison of the hood sizes, small, medium and large.

I've never noticed one type of hood being more valuable/collectable than the other, in my experience they all sell for pretty much the same amount, condition being the most important factor, and whether they come with or without their weapon.
