1. Title: "A Glimpse into the Historical Blanching Room: Polishing and Drying Coins of the Royal Mint, Circa 1910" In this evocative photograph from the annals of numismatic history, we are granted a rare peek into the blanching room of the Royal Mint, circa 1910. This room, a vital component of the coin production process, was where the annealed blanks underwent their metamorphosis, transforming from rough, unfinished metal discs into gleaming, polished coins. Annealing, a crucial step in coinage production, involved heating the blanks to a specific temperature to soften the metal, making it easier to work with. Once annealed, the blanks were transported to the blanching room for the next stage of their journey. In this room, the blanks were subjected to a series of revolving drums, where their surfaces were meticulously polished. The drums, filled with an abrasive compound, gently yet persistently rubbed against the metal, smoothing out any imperfections and imparting a uniform shine. After the blanching process, the coins were carefully dried in these revolving drums. The drying stage was essential to prevent the coins from sticking together during the striking process, ensuring each coin emerged with its unique, individual character. This photograph offers a fascinating glimpse into the rich history of coin production, showcasing the intricate and labor-intensive methods employed during the early 20th century. The room's regal atmosphere, with its high ceilings, large windows, and ornate machinery, underscores the importance and grandeur of minting coins, an enduring symbol of trade and economic prosperity.
