Our take on the JSA Larry Bird Signed Boston Celtics Jersey (JSA Certificate of Authenticity)
A Boston Celtics jersey signed by Larry Bird, sold with a JSA certificate of authenticity. The JSA COA is the main draw: it gives buyers a documented third-party opinion on the signature, which matters most for resale. At $299.99 at Amazon as of November 4, 2026, it is the lowest of the three new prices tracked. The jersey itself is a signed collectible, not a game-worn or game-issued piece unless separately documented.
