In May 2026, the National Regional Newspaper Alliance (47 member papers) simultaneously launched a monthly joint feature on the theme of Regional Monetary History and the Modern Economy. Each paper is uncovering old coins and monetary history connected to its region while visualizing links with regional economies, tourism, and collector culture in a unified format, achieving large-scale reach of old coin information to regional newspaper readerships (ages 50–70).
