2.5 Gram Gold Bars
A 2.5 gram gold bar is a .9999 fine two-and-a-half-gram bar, assay-sealed from refiners like PAMP Suisse and Valcambi — a small, giftable format with a slightly lower premium per gram than a 1 gram bar.

About 2.5 Gram Gold Bars
2.5 gram gold bars occupy a practical middle ground in the gold bar market — larger than the 1 gram format yet compact enough to remain highly accessible by price. Each bar contains 2.5 troy grams of .9999 fine (24-karat) gold and is produced by a sovereign or private refiner to strict international purity standards. At this weight, individual bars carry a modest face value relative to full-ounce formats, making them a straightforward way to acquire physical gold in smaller, precisely measured increments.
The 2.5 gram format is dominated by Swiss refiners who have set the global benchmark for small-bar production. Valcambi Suisse, headquartered in Balerna, Switzerland, is among the most recognized names in the segment, producing bars notable for their clean, minimalist design and precise milling. PAMP Suisse — also Swiss — is equally well known at this weight, with their Lady Fortuna reverse design being one of the most recognized motifs in modern bullion. Both refiners typically deliver 2.5 gram bars sealed within a tamper-evident assay card (CertiCard or equivalent), which includes the bar's weight, fineness, and a unique serial number.
At Lone Star Coins, the 2.5 gram gold bar collection currently features bars from Valcambi Suisse and PAMP Suisse, each sealed in original assay packaging.
