He pretty much was saying what I wanted say, the Franklin isn't polished that badly though, on the front... The walker definitely cleaned. Not worth anything more than $6. The Morgan is cleaned and is in XF. Nice coins, bummer they were cleaned though...
Ok, I think I now have a handle on how to tell whether or not morgans have been cleaned. (Unfortunately, a good many of my nicer looking coins are cleaned...but now most are worth about what I paid for them).
I don't feel very confident about some of the other coins though. What about these two?:
Hard to tell on the Merc, but the Walker is cleaned. The Merc shows a little toning unless its just the light the pic was taken in, so if it was cleaned it'd be a long time ago.
