These coins are actually my mothers, though I found the really old one when I was a teenager on my Grandmothers farm thirty years ago. She (Mother) asked mt to see if I could find out anything and that led here. The first is a 1900 silver dollar and the second is 1850 Haiti, not sure of what the other stuff says.
The Silver Dollar is a 1900-O (New Orleans Mint) and is a fairly common coin. In that condition it is worth its value of the silver content (about $24) or slightly more. I know nothing about the Haiti coin. You would have a better chance of getting someone to identify and value this coin if you posted it in the World and Ancient Coins forum.
the second is 1850 Haiti, not sure of what the other stuff says. Hey fundreamer The coin you have pictured is a Haitian 2 Centimes 1830// AN27 not 1850. Made of copper. The AN 27 refers to year 27 equivalent to 1830.
Don't worry about that, he's just shamelessly promoting some group he created. If you really want to learn about coins, just read... there's a huge wealth of information scattered about on this forum.
