Getting to the heart of what makes a Silver Dollar authentic and valuable often starts with a simple, yet crucial, measurement: its weight. The official United States Mint specification for a Morgan Dollar is a precise 26.73 grams. This standard is the benchmark that collectors and experts have relied on for over a century.
This specific weight is a direct result of the coin's composition. Each Morgan is meticulously crafted from an alloy of 90% silver and 10% copper, a classic formula that gave the coins durability for circulation while retaining high intrinsic value. This translates to an actual silver weight of 0.7734 troy ounces per coin, a key figure for anyone tracking the precious metal market.
As you've seen from other collectors, weighing these coins is a common and important practice. Why? Because while a perfect, uncirculated Morgan will hit that 26.73-gram mark, a coin that has passed through countless hands will have lost a tiny fraction of its mass due to wear. A slightly lower weight is perfectly normal for a circulated coin. However, a significant deviation can be a major red flag, potentially indicating a counterfeit. By placing a Morgan on a scale, you're doing more than just measuring metal; you're taking a critical step in verifying its history and authenticity.
