Here's the same coin on eBay with the infamous "real or fake?" disclaimer: http://cgi.ebay.com/1776-Continenta...36?pt=Coins_US_Individual&hash=item3a67c3b928
It looks like the kind of reproduction that is sold at historical theme parks and tourist shops in historical areas.
I wouldn't, it is fake. No further review is required. His images are good enough to be certain that the diagnostics of a genuine piece are all missing and that it exhibits a number of the common characteristics of a mediocre cast counterfeit. There is no doubt on this coin, it is not genuine.
I agree, I would not go out of your way or spend money having it looked at. If you want OP, if you happen to be at a show and wish to get a second opinion, please feel free. However, I agree there is zero percent chance this is authentic.
