Trade volume for NBA Top Shot’s nonfungible tokens (NFT) has skyrocketed over the weekend following the launch of its retro “Run It Back 2005-06” packs on Friday.

According to Crypto Slam, daily volume on NBA Top Shot’s marketplace jumped by more than 440% from $829,520 on Thursday to more than $4.5 million the next day. Saturday also saw more than $4 million worth of tokens trade hands.

NBA Top Shot’s NFTs feature video highlights depicting key moments from the history of professional basketball, with the latest packs celebrating the stars of the 2005–2006 season.

On Sunday, NBA Top Shot tweeted that nearly 10,000 “Run It Back 2005-06” packs had been sold in 24 hours at a rate of seven purchases per minute.

The packs started at $169 each, with collectors competing to snag moments depicting basketball legends such as LeBron James and Shaquille O’Neal. NBA Top Shot’s packs feature three tiers of rarity ranging from “common” to “legendary.”

Crypto Slam data shows that the NBA Top Shot marketplace has hosted a whopping $744 million worth of secondary sales since July 2020. NBA Top Shot trade activity peaked during the first quarter of 2021, with $45.7 million worth of trades occurring within 24 hours on Feb. 22.

While more than $200 million worth of NBA Top Shot NFTs changed hands during the months of February and March, the monthly volume has since retraced sharply, with approximately $20 million of trades taking place during September and October.
