I would appreciate it if someone could help me with a guestimate as to the
value and background of this coin. I am not a coin collector, but have
always have had a mild fancy for older coins. :-)

Anyway, I was recently in San Francisco in a jewelry shop and came across a
box of loose oriental silver dollars (trade dollars, mostly). Rummaging
through them, I found several 1843 Seated Liberty Dollars with most being
heavily worn.

I found this one specimen that would likely rate as being in "fine"
condition. (sorry for the ambiguity, but that is the extent of my grading
knowlege). Here is my problem:

The reverse of the coin has the banner "IN GOD WE TRUST" over the eagle's
head. Otherwise, it looks just like any other 1843 seated liberty silver
dollar. I cannot find any 1843 seated liberty dollars that carry this
banner.

The coin does not appear to be a fake and has certainly seen circulation.
Any help concerning this coin would be most apprectiated.

Thanks in advance!
