Based on official United States Mint specifications, a silver dollar in uncirculated condition has a standard weight of 26.73 grams, or approximately 0.943 ounces. This weight is a result of its composition, which is 90% silver and 10% copper.
The actual weight of any specific coin can vary slightly. A brand new, or mint state, Morgan dollar should be very close to the 26.73-gram standard. However, coins that have been in circulation will often weigh slightly less. This is due to the minor loss of metal from friction and wear over many years of being handled.
For collectors, weighing a Morgan dollar is an important step in authentication. A coin that is significantly underweight compared to the 26.73-gram standard could be a counterfeit, as fake coins are often made from less dense, non-precious metals. Conversely, a coin that is significantly overweight is also highly suspicious.
