A super rare card that features an NBA Logoman patch from one of LeBron James' jerseys during his epic 2016 Finals series has just gone up for sale ... TMZ Sports has learned.
PWCC officials tell us they put the card on their auction block Thursday ... and it's truly a one-of-a-kind item.
It's a Panini Eternal piece that was created just after the trading card co. scored one of LBJ's jerseys from the series against the Warriors where he came back from down 3-1 to win Cleveland's first title.
Panini cut the NBA Logoman patch from the threads -- built it into the card ... making it a true 1-of-1.
No word on what it's ultimately expected to fetch when the final gavel hits ... but PWCC exec Jesse Craig called it "one of LeBron's best cards" ever.
"Outside of some rare booklet-style cards, this is the only series of cards I am aware of that included LeBron James NBA Finals-worn jersey pieces in them," Craig said.
"It's of interest to see it go to auction right now because of the playoff battle between LeBron and Curry. That 2016 Finals is the notorious 3-1 Golden State lead that LeBron and the Cavs overcame to secure their elusive championship. This card was constructed as a monument to the victory of King James."
Bidding on the card -- which is graded Mint 9 and features James holding the Larry O'Brien trophy with a short blurb about his legendary Game 5 performance on the back -- ends on May 25.
Good luck, bidders!!
