A piece of Kobe Bryant‘s legacy is no longer on the market … the warm-up jacket he wore before his last-ever NBA game has just sold at auction — and it netted the seller a small fortune!

TMZ Sports has learned … the threads the Black Mamba donned just prior to dropping 60 points on the Utah Jazz back in April 2016 at the Staples Center racked up 35 bids — and officially sold for $336,000.

The jacket — which was photo-matched for authenticity — had been up on the SCP Auctions block since mid-July.

The gold Adidas, size XL piece is awesome … it features purple accents and patches that celebrate historic moments in the Lakers’ franchise history. From their 31 conference titles to their then-16 championships — it’s clear why someone threw down some serious dough for the prized possession.

As for how it helped Kobe, it all played a part in his storybook NBA ending. The legend drained 22 of his 50 shots from the field on the night … while shooting 10-12 from the free-throw line.

After the remarkable performance … Kobe thanked the fans for their love and support — and hit them with a now-iconic line — “What else can I say? Mamba out.”
