Interesting fact

One interesting fact about the Tostão "I- Λ"– João III (2nd type, Porto) ND (1540-1555) coin from Portugal is that it features a unique design element - a small letter "i" or "λ" (lambda) above the king's crown on the obverse side. This letter is believed to represent the mint master's initial or a secret marking to indicate the coin's authenticity. This feature is not commonly found in other coins of the same era, making it a distinctive characteristic of this particular coin.
