So do I -- just not on me. Super-nice! Maybe one day I'll own a bust dollar, but likely not this early nor this nice.
The 1799 is the most common date. The dollar was the only silver coin the mint made bearing that date.
And the only other denomination minted that year was the large cent, listed in the current red book at $3,500 for an AG-3! The 1799 S$ is listed in the current red book at $900 for a G-4. edit: the 1795 S$ is listed in the current red book at $960 for an AG-3.
That is a very nice example of the off-center bust, and a nice picture as well. One can see you chose judiciously. If I remember correctly, that is the B-5 variety? I have an example of the same variety, but in much lower grade. Pity the slab is so scruffed up.
Here is a picture of my 1795 Bust Dollar. You can see that it is not as nice as yours. It also was the first photo I took of a coin, in the bank when I was looking at my safe deposit box, which is where it resides. You can that it is not a well struck piece, with wear on the face and some on the reverse. I figure it is about an EF-40. My pictures are not very good. I will try to take some more. What do you think it is worth and grade. It has been in the family for over 150 years. I came into it in the 1950s when I asked my grandmother if she had any old coins. She brought out a cigar box with this coin and maybe 50 large cents, the oldest of which was 1804, most from the 1830s.
That's worth taking the effort to get some good photos and posting them here. With good photos, a number of us can offer opinions on grade, and the variety as well as opinions on authenticity and value. If you are unsure how to take good photos, rest assured people here can help.
@CoinTalkJim It appears to be a nice coin, but I would need better pictures with better focusing to give you an estimate of value.
