More collectors entered the hobby during the 1980s. As a result, manufacturers such as Score (which later became Pinnacle Brands) and Upper Deck entered the marketplace in 1988 and 1989 respectively. Upper Deck introduced several innovative production methods including tamper-proof foil packaging, hologram-style logos, and higher quality card stock. This style of production allowed Upper Deck to charge a premium for its product, becoming the first mainstream baseball card product to have a suggested retail price of 99 cents per pack. In 1989, Upper Deck's first set included the Ken Griffey, Jr. rookie card. The card became highly sought-after until Griffey's persistent injury troubles caused his performance level to decline.
