The way former President Reagan (search) and his wife, Nancy, would carry on about their love for each other, one might have gotten the impression their romance was carved in stone - and it turns out it was.

A part-time estate liquidation consultant who was looking for anything the Reagans might have left behind at a Pacific Palisades (search) home they lived in 50 years ago recently uncovered a slab of concrete. Carved into it was a heart and the initials "ND (for Mrs. Reagan's maiden name, Nancy Davis) and "RR."

"I got a hose and washed it off and said, 'Oh my goodness,' " recalled Terre Hirsch (search).

Instead of rushing to eBay with his treasure, he decided to turn it over to the Ronald Reagan Presidential Foundation. The former first lady, whose husband died last year, couldn't be happier.

"Mrs. Reagan remembers well the day her husband drew a heart with their initials inside in the concrete patio of their home ... ," the former first lady's office said in a statement.

"In a time when so many people are motivated by financial gain, she was moved and very grateful that Mr. Hirsch offered the piece to her," the statement added.

The slab, nicknamed the Amalfi Valentine because the Reagans' former home sits on Amalfi Drive, is expected to go on display at the Ronald Reagan Presidential Library in Simi Valley this fall.
