Spanish Colonial America Potosi Mint
The Potosi mint in present-day Bolivia was established in 1574 and became one of the world’s largest producers of silver coins. The colonial mints produced irregular coinage called cobs. Cob comes from the Spanish word “Cobo,” meaning bar or ingot.
Silver was cut into chunks of the appropriate weight and then struck with a hammer between crude dies. The cobs’ size, shape, and impression are highly irregular, but they were the proper weight. Often only a small portion of the image from the die was imprinted on the silver. The most important feature of any cob coin is the date. If your cob has an intact date, it is worth much more than a cob where the date was never imprinted on the piece of silver.
