Hit

From BaseballCardPedia.com

Hit: a high-value insert card, usually a card that is either serial numbered, autographed, or game-used. Hits vary in value by the product and by the purchase size. A "case hit" in 2012 Topps Tribute, for example, is likely to be a card that would sell for hundreds or even thousands of dollars; a "box hit" in, say, 2010 Topps Series 1 could sell for ten dollars or less.
