This is a very solid piece of bullion. Specifically, it's a 100g Silver Minted Bar from Baird & Co., a well-established British refiner. ​Here is a breakdown of what you're looking at and why it matters for its value: ​Bar Specifications ​Refiner: Baird & Co. (London). They are members of the London Bullion Market Association (LBMA), which is a "gold standard" for trust in the industry. ​Weight: 100 grams (roughly 3.215 troy ounces). ​Purity: 999.9 Fine Silver, which is the highest standard commercial purity available. ​Security: It is sealed in a CertiCard which acts as a tamper-evident assay certificate. This helps preserve the "mint condition" and proves the bar hasn't been shaved or altered.
