A homeless man who returned a diamond engagement ring to a woman who mistakenly dropped it into his donation cup when she was giving him some spare change now stands to be handsomely rewarded for his selfless act.

"It is good to know honesty still exists despite one's circumstances which Mr. Harris exemplifies!" wrote one poster, who donated $25. Another who gave $100 added: "People from all over the world salute."

The donations – more than 6,000 of them in varying amounts – have come in from all over the United States, as well as from Germany, Sweden, Australia, Ireland, and other countries.

In addition to the congratulations and good wishes that they offered, some donors also urged that Harris receive help to manage the money that was earmarked for him.

Harris himself seemed to be bemused by the outpouring.

"What I actually feel like is, what has the world come to when a person returns something that doesn't belong to them and all of this happens?" he said last week in an interview with KTNV-TV, an ABC News affiliate in Las Vegas.

When Harris saw the unintentional donation in his cup on Feb. 8, he kept it safe until its owner, Sarah Darling, returned to ask about it. Her wedding and engagement rings had reportedly been bothering her, so she removed them and put them into her purse, and that's how they ended up in Harris' cup, KCTV reported.

News of Harris' act – and Darling's gratitude – has spread. KTNV-TV reported that complete strangers have sought Harris out to congratulate him and give him food.

The fund was started 10 days ago by Darling's husband, Bill Krejci. It will close in 80 days, at which time the money will be given directly to Harris, according to a note on the fund's web page.
