Black felt-tip permanent marker (Sharpie) on a white cotton-blend fabric brim.
Item Description
Official Masters Tournament 'rope' hat, white with embroidered Masters logo and green/red detailing.

$150 - $250 USD authenticated; lower as unauthenticated.
Comparison to Known Examples
Matches high-quality exemplars from tournament-signed items circa his 2015-2017 peak performance years.
Authentication Tips
Look for the distinct vertical loop in the 'J' and the specific way he connects the 'S' to the tail of the name without lifting the pen.
Certification Recommendation
JSA (James Spence Authentication) or PSA/DNA are the industry standards for golf memorabilia.
Red Flags
No significant red flags observed. The ink saturation and stroke speed appear natural for the surface.
Provenance Notes
Valuable if accompanied by a tournament badge or photo from the event where signed (e.g., Augusta National or a PGA Tour stop).
Historical Context
Spieth is one of only a handful of golfers to win the Masters at age 21, making his autograph on a Masters hat a quintessential piece of golf history.
Market Trends
Spieth's market is stable but sees spikes during the week of the Masters or when he is in contention for a win.
Investment Potential
Moderate. As a young multi-major winner, he is a future Hall of Famer, making this a solid 'blue-chip' golf collectible.
