What moves the price of this card

The Roseanne's Research (David Cohen) on this page is the Normal printing from World Championship Decks, and it trades at $0.93 in near mint condition. Only one printing of this card was produced, so there is no cheaper version to confuse it with.

Condition does most of the work below the surface. A copy with soft corners or a print line off centre trades well under the market price shown here, and a copy clean enough to grade trades well above it. Before you value your own copy, look at the corners under a light and check the centring on the back, where most cards give themselves away.
