The most memorable item in his home is an unusual find: A chicken egg that a neighbor found in an egg carton in 1951. Written on the egg is a message from a Miss Mary Foss of Forest City, Iowa.

"Whoever gets this egg please write," Foss had written, along with her name and location. Amalfitano said his neighbor held onto the egg for 50 years, without bothering to find Foss or write back.

The neighbor then gave it to Amalfitano, who held onto it for another two decades before sharing photos on social media. He posted pictures of it on a "Weird and Wonderful Secondhand Finds" Facebook page, wondering to the three million members of the group if Foss was still alive.

Foss, now 92 years old, told CBS News that she remembered writing on the egg.
