Lucy said she headed to the Dundalk Citgo in Baltimore, where a clerk who had recommended her a scratch-off ticket that won a $500 prize in September suggested she try a $5 Winning Streak ticket.
The woman took the ticket home to her 36-year-old daughter, who soon discovered it was a $50,000 winner.
The winner had Lucy protect the ticket until they could make plans to visit lottery headquarters with all of the itchy-handed siblings in tow.
"Mom hid the ticket under her pillow," said one of the sisters. "Nobody messes with mom!"
The winner said she plans to use some of the money to send Lucy and her husband on a cruise. She said the rest will go into savings for Lucy's eight grandchildren.
