Hi Pam, you created a duplicate thread of this original one. That usually occurs when you don't see it being created (uploaded) right away the first time you hit the Create Thread button. Just wait a minute or two and it will load. Hitting it 2 or 3 times will create duplicate threads. I reported it to the moderators for it to be removed.
So, is your coin "gold plated" or that just the camera color the photo? When the SBA dollars came out, they were NOT accepted by the public, and several third party companies grabbed a bunch, gold plated them, and sold them as collectable. It seems someone put one in circulation, if that's the case.
