Harvard Law School has made a remarkable discovery in its archives, revealing that a document once thought to be a mere copy of the Magna Carta is, in fact, an authentic original dating back to 1300. The document, purchased for just $27 in 1946, was miscatalogued for over 70 years. British scholars recently confirmed its authenticity, noting that it could be valued in the millions. This unexpected find highlights the significance of historical documentation and the importance of meticulous archival research.
