Yesterday was a big lottery payday in Pennsylvania, with a Philadelphia man claiming an expiring prize, and a teacher from Wyndmoor becoming a multimillionaire.

But those aren't the only major prizes that have gone uncollected.

Here's a rundown of some of the riches:

Claimed: Plymouth Meeting Mall's $46.6 million. Palmira Nicolo, 57, who taught Italian at Cherry Hill High School West, finally came forward, claiming half of Powerball's Feb. 28 jackpot. It was worth $174.4 million in yearly payouts, but both sides opted for cash - $46.6 million, less taxes. The other half was collected in April by two anonymous friends in Delaware. Nicolo, who bought her ticket at the mall's customer service desk, has likely known of her win for a while: On March 24, she applied for retirement.

Claimed: Philadelphia's expiring $200,000. On Wednesday, William H. Greer of Philadelphia stopped by the state lottery's city office to claim a Powerball prize - one day before the deadline. His mother saw a TV news report and told him to check his tickets. "The last one matched the numbers my mother gave me, he said. "I started shaking when I checked the numbers against the Lottery's Web site." He matched all the numbers except for the Powerball on the ticket he bought last June at Choi Beer & Deli on Ford Road in the city's Wynnefield Heights section.

Unclaimed: Lancaster County's $8.26 million. On May 29, someone hit the Pennsylvania's Super 7 jackpot. The winning slip was sold at Royer Pharmacy, 335 W. Main St. in Leola. To win Super 7, you need just seven - just seven - of the 11 numbers drawn. They were 2, 4, 9, 12, 17, 19, 24, 28, 41, 42 and 53. The ticket was the first jackpot win since Super 7 debuted March 13.

Unclaimed: Chester County's $1 million. Did buy a ticket for the June 10 Powerball drawing at the Acme at 907 Paoli Pike in West Chester? If so, and you paid for the Power Play, you may have won $1 million. The ticket matched the first five numbers drawn - 15, 26, 27, 42 and 58. (The Powerball was 37.)

Unclaimed: Burlington County's $250,000. In the June 12 Mega Millions drawing, a ticket purchased at a Mount Laurel Shoprite won $250,000. Matched were the first five numbers - 6, 11, 20, 32 and 44 - but not the Mega Ball (38). The store is at 892 Union Mill Rd.

Unclaimed: Monmouth County's $409,000. A ticket, purchased at the K Food Store on Route 9 in Howell, hit the June 14 drawing for New Jersey's Cash 5 lottery game. The winning numbers were: 7, 9, 16, 17 and 28.

Officials suggest signing winning tickets and consulting financial experts before contacting the lottery to make a major claim.
