The National Football League (NFL) is experimenting with non-fungible tokens (NFTs).

The league says it’s pairing tickets purchased at select games with “Virtual Commemorative Tickets” sent as NFTs to eligible Ticketmaster wallets, according to a press release.

The league also released its first batch of commemorative NFTs through Ticketmaster and Polygon on Thursday, which include 125 different collectibles for each of the league’s 32 teams.

Very interesting to see the subtle design differences on these virtual stubs. I wonder how much say the teams had? (compressed for Twitter) pic.twitter.com/G9x22Eoomb

A source with the league told CoinDesk that the NFL is “experimenting and trying different things to gauge consumer reaction.”

The NFL partnered with Dapper Labs in September with plans to create its own NFT collectible marketplace on the Flow blockchain, similar to the company’s NBA Top Shot product. The marketplace was said to be released by the end of the season on Jan. 9.
