AboutMyCoin1891-S Morgan Dollar in AG3
An 1891-S Morgan dollar graded AG3 is that coin in one particular state of preservation — the date and the mint mark are already fixed, and AG3 is what a grader called the surface that survived. What that looks like on this coin is below. The nearest grade of this date this site does have a researched figure for is Very Good (VG-8), at $78 to $82, from sales and public data.
What AG3 means
An 1891-S Morgan dollar in About Good (AG-3) is worn past the point where the design carries any detail: the hair above Liberty’s ear and the cotton bolls in her cap are gone, the eagle’s breast feathers and the tops of its wings are flat to the field, and the rim has worn into LIBERTY on the headband, E PLURIBUS UNUM and the date so that parts of the lettering merge with the edge. The date is readable, and on a scarce issue that is the whole of what this grade has to guarantee.
A slab, a dealer’s list or a price guide may write this grade AG-3. They are the same grade and the same 1891-S Morgan dollar.
