The Confederate States of America issued two coins in their short history. Genuine CSA one cent and 50 cent coins are worth 1000s and 1000s of US dollars, but there are many counterfeits and cheap imitations.
The CSA did not issue any gold coins. You have instead a novelty piece that sells for a few dollars.
We have write-ups on genuine CSA coins at these links:
- Half Dollar
There is a great web site dedicated to these coins at CSACurrency.com.
To add even more confusion, there are odd denomination pieces kicking around. These are all most certainly fakes and reproductions designed to fool unwary tourists during their treks through Dixieland. As far as I know, all are worthless, or of low value.
