2016 Worlds Staff card

What is a fair ungraded price for this card?

I’ve seen them sell between $30 and $50. They’re pretty slow to sell in general. Unlike a lot of other events with STAFF promos, at Worlds the STAFF is a lot higher in print and cuts close to even the players unstamped promos for some years. So they don’t get much of a premium, if at all. I’ve never paid more than $30 myself.
