Pennies and the Piano

My mom inherited my grandparents piano. It is beautiful and holds beautiful memories. She gifted it to my brother last year. He plays beautifully. Salina hired a friend to come and tune the piano. Inside was a few pennies from long ago. We all thought it was neat to think about how they got in there. Did one of my uncles playing around stuff them inside? Did my grandpa come home from work and set his wallet down and it spilled pennies? We are hoping they are rare and can help my mom with money. I loved this piano. Each Christmas we would sing with all my cousins. It is the piano I learned to play on. it is now the piano I am trying to relearn to play on.
