Field Index — Game-worn, game-used, historic items

Sports Memorabilia — Realized Sales Index

Sports memorabilia covers game-worn jerseys, game-used bats and balls, historic championship items, and trophies. Photo-matching has become the single most important authentication advance in the category — game-worn items with documented photo-match consistently clear 3–10x the price of unmatched equivalents.
