The founders of a Las Vegas mob attraction are launching mob-themed nonfungible tokens encompassing digitized versions of real-world organized crime memorabilia.

Dubbed “The Mob Experience,” the collection includes NFT versions of artifacts that belonged to some of America’s most notorious gangsters. The artifacts include a hand-written note from Al Capone to his son, written from Alcatraz; the hand-written diaries of Meyer Lansky; Bugsy Siegel’s handgun, and Mickey Cohen’s brass knuckles, among other historical pieces.

The collection will be auctioned over a two-week period starting on Thursday, according to a recent press release. But given the dramatic turn the NFT market has taken in the past month, is “the mob’s” arrival on the token scene a little bit late?

Data from Nonfungible.com reveals that almost every measurable metric relating to the sale of NFTs has plunged of late. The frequency of NFT sales dropped 30% over the past month, from 179,656 to 124,371.

Meanwhile, the total value of NFT sales measured in United States dollars dropped 15% from last month’s rolling average of $229,945,000 to the most recently measured data point of $193,261,000.

The number of active NFT wallets decreased 24% in the same period, while the number of unique buyers of NFTs dropped by the same percentage.

A recent Bloomberg report suggested that the average value of each purchased NFT dropped 70% moving into April. From a February high of $4,300, the average price paid for an NFT dropped to $1,400 just a couple of months later.

The Mob Experience’s decision to enter the NFT market was sparked by cryptocurrency investor Michael Evers. Evers talked up the rarity of having a museum-quality collection converted into NFTs.

“Never before has a museum-quality collection been tied to the NFT market. The opportunity for Mob fans and collectors, as well as NFT owners, to be the only one in the world to own an extraordinary and unique, one-of-a-kind piece of history is an exciting new first for the NFT marketplace,” said Evers.
