I Attended an Estate Auction this past weekend with a friend looking for some furnature. Insie a box on the table was a plastic coin sheet containing 8 silver dollars. I inquired as to their price. The lady sid 20 $. I knew they were worth at least 5 dollars each just for the silver content so I bought them. I drop dead gorgious lady came into the room and my attention was shifted in her direction. I slipped the coins into my pocket and forgot about them. Today I tried to determine their approx. worth and was unable to figure out a particular one. Any help is appreciated.
A 1797 sitting Liberty Silver Dollar. It is marked 420 grains 900 fine with a CC mint stamp. It is a
Trade dollar. Now that's where I get so confused !

I researched
Trade dollars and the references all seem to state they dated back to about 1850. Mine goes back 50 years before any record I can find. Can anyone explain this to me in Newb language ?
