NEW YORK (CBSNewYork/AP) — An unusual money giveaway that’s made headlines around the country and is causing an international frenzy on social media may be coming to New York City.

An anonymous man with the Twitter handle @HiddenCash has been hiding money across San Francisco since Friday, leading scores on a scavenger hunt.

The man says he has made millions in the San Francisco real estate market and has been giving some of it back in the form of $20 and $100 bills stuffed in envelopes hidden around the Bay area.

He said his giveaways are a “social experiment for good” and hopes that winners also “pay it forward.”

Clues to the money’s location are posted on Twitter and his following exploded from a few hundred Friday to more than 80,000 and counting by midday Tuesday.

One of his clues Tuesday told San Francisco followers to “find Mr. Franklin along the ‘crookedest street,’ (towards the bottom).”

Translation: There was a $100 bill at the bottom of Lombard Street, the popular touristy thoroughfare that’s best known as the “Crookedest Street in The World.”

@HiddenCash said on Twitter that he plans to leave envelopes in San Jose on Wednesday, Los Angeles this weekend and maybe New York City next month, giving away a $1,000 a day.

Followers have requested similar gestures in Alabama, Washington, D.C., and as far away as Pakistan with various hashtags ranging from #kindness, #generous, #epic and #strange.
