This is a beautiful piece of bullion! What you see is a 100g Poured Silver Bar from the The Gold Exchange (TGE) based in England. ​Cast or "poured" bars like this are popular with collectors because each one has a slightly unique texture and shape compared to machine-stamped bars. Here is a breakdown of what the markings on your bar tell us: ​Bar Anatomy & Authentication ​The Hallmarks: On the left, you can see the circular TGE (The Gold Exchange) logo. This identifies the refiner/distributor. ​Purity: The bar is stamped .999 SILVER, which is "fine silver"—the standard for investment-grade bullion. ​Origin: The prominent Union Jack flag and the text "MADE IN ENGLAND" indicate its manufacture. ​Weight: While the image is a bit tight on the text, these specific bars are typically 100 grams (roughly 3.215 troy ounces).
