Ah, I see others have said it's a fake. Which is what I was about to say.
A little bit of experience will help you greatly, don't get too worked up. Hopefully you can learn from this mistake.
If you're interested in collecting
Trade dollars, buy only from a dealer you trust. Also, I'd suggest that until you've studied quite a few and you know what to look out for, you might only buy certified coins. I suppose that goes for all coins, but especially
Trade dollars.
I only hope you didn't get burned too badly. Would be a terrible waste if you got quickly turned off to coin collecting by one bad experience!
