I'm not sure some of the things that were magical years ago would seem so now.
I mean, I remember some hilarious craziness when we got a decanter of endless water. And one guy who loved his +1 unbreakable staff (which I think the DM just made up and winged whenever he tried to use it to block stuff or whatever).
And, whoa boy, rods of wonder.
But it's more old hat nowadays. I'm not sure we'd see the same reactions.
If you thought about the items from any edition that really felt magical, what leaps to mind? Maybe narrowing the field to what work(s/ed) will help.
