Normal helmet, nothing special. It looks cool though, as you pointed out. I'll give you a description of each type of helmet so you know what's magical or what's not.
Model 1: the standard model you buy in stores with 2 horns
Model 2: a decorative helmet that resembles that worn by Flaming Fist Guards, a simple cylindrical helmet with a single tail of hair coming out of the top. It has a cross shaped hole to see out of.
Model 3: a decorative helmet resembling those worn by the watchers of Candlekeep. It has two furry things (I don't know what else to call them) coming out of the helmet, sort of like horns with fur on the sides. It has a single slit for eyeholes.
Model 4: a decorative helmet (lots o' decorative helmets eh?) that is the one you got. My second favorite helmet in appearance.
Model 5: a decorative helmet (yes, another one) with cheek guards, open face, with large fins protruding from the sides. Personally, my favorite looking helmet. These are worn by Amnish soldiers.
There are a couple exceptions to these general rules. The most notable one being the Helmet of Infravision. It looks like Model 3. If any helmet is unidentified, then it's magical.
You can always find a way to elaborate things Ramon and a reason, see
