What is a signed index card?

A signed index card is a standard 3x5 index card bearing a player's authentic autograph. These were historically obtained in person at ballparks, hotels, or events. They are authenticated by industry-leading services and make excellent additions to autograph albums or framed displays. Each card from Pristine Marketplace includes a COA and tamper-evident hologram.

Why collect signed Twins index cards?

Index cards offer an accessible entry point into authenticated memorabilia, often at lower price points than signed baseballs or jerseys. They are also among the most common formats for vintage autographs, making them essential for collectors seeking signatures from players of earlier decades.
