Harold Hamp was putting a roof on a home in Alma in 1968 when he lost his wallet. It was found 44 years later by another man re-roofing the same house.
The Oakland Press in Pontiac reports that Casey Morgan spied the wallet buried in attic insulation.
It appears the wallet fell from Hamp's pocket, tumbled between roofing boards into the attic where it rested for more than four decades.
Morgan's boss Terry Thelen later tracked down Hamp's name through an Alma telephone book and reached his son.
Now 78, Hamp says "we got back all of the pictures, and several of the bills in it were silver certificates."
The wallet also held other papers and $23 in currency.
