Spain. Carlos IV. 8 Reales Acuñados en ceca de México, 1808. Ensayador T·H. (No reserve price)

The 8 Reales coin from the reign of Spain's King Carlos IV, minted at the Mexico City mint in 1808, is a significant example of Spanish colonial currency. The 8 Reales, often called the "piece of eight," was widely used across the Spanish Empire and internationally during the 18th and early 19th centuries. These coins were made of silver and renowned for their consistent weight and purity, which made them a trusted currency in trade across the Americas, Europe, and Asia. The Mexico City mint was a major facility producing these coins, often stamped with mint marks and assayer initials, in this case "T·H." Collectors value these coins for their historical importance as they represent the extensive reach of Spanish rule and early global commerce. This coin also reflects the artistry and standardization of Spanish colonial minting during a period of significant political and economic change leading up to the independence movements in Latin America.
