Could be in a shoebox.

That envelope stuffed with old wallet receipts.

Maybe it fluttered under the driver's seat.

Wherever it is, find it fast and check the numbers!

We're talking about two lottery tickets.

Each is worth $50,000 - now.

Soon they won't be worth a cent.

One was a Quinto ticket, purchased last Dec. 19 at A&C Johnson's News on West Passyunk Avenue in South Philadelphia.

The winner had all five of these numbers in the evening drawing: 5, 1, 8, 9 and 7.

The other was a Powerball ticket, bought last Dec. 27 at Dugan's Store in Jim Thorpe, Pa.

The slip had four of these numbers - 12, 15, 26, 31 and 43 - the Powerball of 10, and the Powerplay multiplier option, which was 5.

Do not wait until the anniversaries of those dates to file a claim, because weekends and holidays have shrunk the window of opportunity.

Since the Quinto prize expires on a Saturday, the in-person deadlines hit the afternoon before - 4 p.m. at lottery headquarters in Middletown, Dauphin County; 4:30 p.m. at any of lottery's seven area offices, including Philadelphia's, at 700 Packer Ave. (Phone: 215-952-1123.)

Last chance: Mail the signed original ticket so it's postmarked by Dec. 19 to: Pennsylvania Lottery, Attn: CLAIMS, 1200 Fulling Mill Rd., Suite 1, Middletown, PA 17057.

Because Dec. 27 is a Sunday, following Christmas falling on a Friday, the Powerball claim must be made in person by Dec. 24, or postmarked by Dec. 26.

Generally, officials advise signing the back of a winning ticket right away, then calling the lottery about a claim at 717-702-8146.

If the amount is a life-changing fortune, getting professional financial or legal help is usually advised.
