In a twist starring Harvard and the $27.50 Magna Carta, a document long dismissed as a replica is now confirmed as one of seven true originals issued in 1300. For decades, a vital piece of royal history gathered dust under fluorescent lights—a scholarly surprise fit for a king.

Forgotten in Harvard’s archives, this 14th-century treasure went unnoticed until experts spotted clues linking it to King Edward I. Rare documents market fans will marvel at the payoff: centuries of legal history camouflaged as campus clutter, now restored to glory and academic awe.
