Hi All,

What are the acceptable weights for genuine Morgan dollars.

I beleive that the weight of a Morgan should be 26.73g, could the weight be higher? if so up to what weight? and if the coin was in AG, or G condition (well worn) what would the expected weight be?

Thanks

26.73 grams is correct

The U.S. Mint spec. for silver dollars from 1840-1935, excluding the Trade dollar type: weight=26.730g / tolerance+0.097g
You could expect a variation of weight even on a substantially worn example to be <1g.

Difficult to really answer accurately since the amount of wear can vary extensively. As already noted could be as much as a gram lost. As to the weight being higher, that could depend on if corroded since corrosion is the addition of some outside substance and that too could vary extensively.

I would agree with Judd1552's answer.

I pulled out my old Ohaus beam balance (quite accurate to about 0.05 grams) and checked weights of 33 circulated Morgan dollars. The grades (my opinions) ranged from Good-4 through AU-58. Every coin that I judged to be grade VF-35 and above weighed in the narrow range of 26.50 to 26.75 grams. The lightest weights I found were 25.7 grams for a Good-4 example and 25.75 and 25.85 grams for two Good-6 coins.

The maximum loss from the standard Silver Dollar weight (26.73 grams) was 1.03 grams for the lowest-graded Good-4 coin. This represents a weight loss of (1.03/26.73) X (100) = 3.85%. Compared to, say, Barber quarters and halves (which can easily be 6-7% light at the Good-4 level) the Morgan dollars appear to retain their silver content pretty well as they wear.
