South Carolina Rotarian Roger Ackerman watched his mother-in-law slowly lose herself to Alzheimer's over two decades. Over lunch one day in 1995, Ackerman’s friend told him that $8 billion to $9 billion in coins changed hands every day in America. Early the next morning, he jolted out of bed, realizing that pocket change could be the key to a cure for Alzheimer’s. This audio version of ⁠a story in the May 2023 issue⁠ of ⁠Rotary magazine⁠ is narrated by Scott Thomas.
