Someone in the Keystone State is half a billion dollars richer. A winning Mega Millions ticket from Friday night's drawing, was sold in Pennsylvania with an estimated prize of $515 million, according to a press release from Mega Millions.
But, no one has yet come forward to claim the winnings, a Pennsylvania lottery spokesperson told ABC News Saturday.
The ticket matched all six white ball numbers drawn on Friday -- 6, 9, 17, 18 and 48, plus the gold Mega Ball 8.
Yesterday's win marks the third-largest Mega Millions jackpot of all time and the largest ever in Pennsylvania, according to Mega Millions.
On Jan. 22, a group of players in Michigan won a $1.050 billion prize. The winning ticket was sold at a Kroger in Novi, a northern suburb of Detroit -- about a 30-minute drive from the city -- the state lottery website confirmed. The winning numbers were 4-26-42-50-60 with a Mega Ball number of 24.
And on Feb. 16, a New York couple won $96 million.
There were other winners of small prizes as well, in Friday's drawing. There was a total of 1,702,748 winners at all other prize levels, according to the Mega Millions web site.
"Fifty-three tickets across the country matched four white balls plus the Mega Ball to win the game’s third prize. Ten of those are worth $30,000 each because they included the optional Megaplier (a $1 additional purchase available in most states); the Megaplier for this drawing was 3X. The other 43 third-tier winning tickets are worth $10,000 each," Mega Million's press release stated.
Mega Millions is played in 45 states plus the District of Columbia and the U.S. Virgin Islands.
The identification of Friday's winner has yet to be disclosed nor the location of where the winning ticket was sold.
In Pennsylvania, lottery proceeds go to programs assisting the state's older residents, including senior centers, prescription assistance, transportation, property tax and rental rebates, and care services, ABC News Pennsylvania affiliate, 6abc, reported.
