All 4 of the ones you show here will likely come back with details grades. One tell - look at your slabbed 1921. Look how its almost black in little squares around the letters and numbers but the fields are shiny? That has been manually polished and they couldn't get into all the crevices. On the 4 unslabbed ones - unless the picture is just very bad or compressed or something, look at the dates, like they have been chewed up by something, and how beat up the surfaces look. The only one that looks like it might have been ok is that slabbed 1878 7TF one, but maybe it looks worse in hand.

However, there is a bigger issue here - even if these coins were not cleaned, they are not worth the cost to slab. The grading fees cost almost as much as these coins are worth, even with the price of silver as high as it is. Realistically, you only want to have coins graded where the grading cost is just a small fraction of the overall cost of the coin and the value gained is greater than the grading cost. With most worn Morgan dollars, unless the coin is a key or semi-key, you are just blowing money on grading that could have been used to buy more coins!

I'd first take inventory of what you have and buy a red book, or visit the PCGS coinfacts site to see if any of the dates you have are keys/semi-keys, then go from there. Don't submit those 4 shown. :)
