1. Sell the box sealed.
2. Keep the box and sell the box sealed in 2020.
Anything that deviates from 1. and 2. is a poor idea.
I think that I have to agree with Commandant on this one.
The thought of doing a Legends draft has been
mentioned before on this forum with minimal interest. Outside of the nostalgia trip and the rare opportunity to do something out of the ordinary, it doesn't seem like a great call.
I have
a friend that's putting together a 9.5 BGS set of English Legends. He has opened two boxes of sealed English Legends solely to find cards that are in immaculate and pack-fresh condition. In that video, you can see how a few of the packs turn out to be fantastic, but most of them turn out to be simply miserable. I think that the only worthwhile reason to open a sealed box from 1994 or before would be if the owner was also trying to put together a highly graded set. Otherwise, a lot of money would likely be lost.
(It's fun to note that the uncommons were oddly divided between two different box runs. There is one very noteworthy difference between the two variants: The boxes that have packs with a Karakas in them won't have any packs containing Mana Drains, and vice versa. My friend has opened two boxes and they were both of the Karakas variant.)
As for the actual
drafting of the set... even with the "experience" and enjoyment factor taken into consideration, it's still probably not worth it. Somebody in my previously linked thread noted that red only has one creature that can attack in the common slot. I mean, if it's something you really want to do with a few friends, I'm sure you'd have a blast. I'd encourage you to film it.

I hope that you'll end up making the right call with your box. It's a great piece of history.
