"I matched five-of-five numbers on one ticket, but I didn't realize it was the one they were looking for," Stover said in a statement provided by the lottery.
Lottery officials say Stover took her winning ticket, which she thought warranted a $100,000 prize, to a local Lottery retailer on May 22.
The retailer informed Stover the ticket was worth $400,000, and then mailed the claim to Lottery headquarters in Middletown, Dauphin County. The claim arrived at Lottery headquarters Wednesday morning and was validated.
Stover's ticket correctly matched all five white balls, 10-18-22-37-45, for a $200,000 prize, and because the ticket was purchased with the PowerPlay option, the multiplier for that evening's drawing - two - doubled the prize to $400,000, less 25 percent federal withholding.
The ticket was sold at a grocery store, which will get a $500 bonus for selling the ticket.
