Kitty,
Thank you for the info. Those are some very cool coins that you posted. The Daniel Sedwick site is very interesting, and there is some very cool "treasure" on that site. As far as being specifically interested in shipwreck coins, my interests jump around quite a bit to things that have an interesting history to them. The 8 Reales that Templar posted hits home being the first silver dollar used in the US. While doing a little more research on them, I found the story of the El Cazador Shipwreck coins, and that caught my interest. It seems that I can get the history of both in one coin

I am a little hesitant to buy a non-graded 8 Reales yet, since I do not believe that I could spot a good fake, and they seem to be faked a lot. As far as the silver cobs, I think you may have opened a new can of worms for me with that last post. The coins on the Sedwick site are very interesting Hmmmm, new collection - I think so.
