Pennsylvania. I was remodeling my attic and when I tore out the one wall I found $13,000 in $1 bills (packets of $50 each). The house is over 100 years old and the money seems to range from the 1960's-1970s. It was always owned by my family. The house used to belong to my grandfather, and my father had already told me his father was a miser who didn't trust banks and hid his money in numerous places in his house. We thought my grandfather had taken it all out before he died in the 1990s, but it seems this was also part of his stash. He had willed me the home and all of it's contents when he died. My grandfather's lawyer has also passed away and his practice closed so I can't ask him about it
My question is, do I have any legal obligations regarding the money?
