An Amulet of Talos would be nice. I think I would like a Dragonbone Sword.
Staff of Magnus, though it would be pretty useless IRL.
Does Lydia count? No? Oh... okay...
I'd like a Dragon bone bow
Dwarven sword. Best looking sword in the game IMO.
I think a Statue of Dibella would look nice on the mantle above my fireplace.
I want a replica of the Steel Sword. Such a fine weapon. Same goes for an Iron Helmet.
What about if the power goes out? Could you imagine? Just whip out the Staff of Magnus and save the day
I'm gullible enough for a necklace of disease immunity to have a placebo effect on me. So, one of those.
A shield from each hold, make a nifty collection.
I also wouldn't mind two glass battleaxes and a shield to mount on the wall.
The Oghma Infinium, preferably the hardcover edition.
All dragon priest masks, the ones from the dragonborn dlc too.
I kinda expected that Beth would come up with Merchandise, for Skyrim and then back up and do some of the other games as well.
Arvak...
don't have to feed him, he can disappear when not needed... I'd save a fortune on gas....
then again... the Church would likely try and have me killed... being able to summon a demonic horse and all...
on second thought, I'd go for an Eye of the Falmer... a gem that large could buy me a new house....
Crown of Barenzia
Finding random gems in public toilets? Hellllo early retirement!!!
Oghma Infinium.
edit:
And Ysgramor's axe, Wuuthrad.
