Very small coin. Front looks like maybe Christopher Columbus. Back says Columbian Exposition and what appears to be 1492 along with some other characters that cannot be made out. Can anyone tell me what it is? I would really appreciate any help. I found the coin in a box along with a 1648 lion dollar and some early 1900s coins from around the world. This is the only one I can't figure out. http://i3.photobucket.com/albums/y81/Mr_Wiggles/2011-04-25165311_Prattville_Alabama_US.jpg http://i3.photobucket.com/albums/y81/Mr_Wiggles/2011-04-25165326_Prattville_Alabama_US.jpg
