I like 1881 as that was the first Morgan silver dollar I got when I was like 8 - 10 years old. I have a few. With "NO" mint mark, yours was stamped in Philadelphia. You still have a nice Morgan !
Approx. 9,163,000 minted with "No" mint mark.
I do a lot of collecting of Morgan silver dollars. I usually see ones of this year with the no mint mark going for about $22-$28 range. The scratches on the face look kind of deep. The collector group on Ebay would probably try and get it if the bid was low enough and it was ending soon. The groups that are just looking for junk silver would probably try and get it around $19-$21ish. The ones just buying junk silver usually try and get them as close to spot as possible.
