What moves the price of this card

The Mansherry on this page is the Normal printing from Royal Blood, and it trades at $0.09 in near mint condition. The same name is on 4 other printings: Awakening of the New Era OP05-088 at $6.19, One Piece Promotion Cards OP05-088 at $2.87, Royal Blood Release Event Cards OP10-056 at $0.60, Awakening of the New Era OP05-088 at $0.31, so read the set, the number and the rarity together before comparing prices.

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.
