1776 Continental Curency Coin

So here's the scoop,
I found this coin in my moms jewelry. Box and saw 1776 on it, I asked her about it and she said she didn't know anything(she wouldn't even know the importance of that date)

I've done 3 hours of research now and realize its probably going to be fake, however, it is worth to much not to get it checked out.

For starters my coin is the one with currency spelt with one R.
It does not have copy writen anywhere on it
I don't know what Ind of metal it is I'm not good with knowing that kind of stuff, however, when I flip it, it does not sound like a thin coin that does the tingggg.
I have not weighed it
It does not seem to be made with two types of metal stack on each other

I apologize for any spell check errors in advance knowing that my phone is bad about that.

Ill post some pictures in a minute or so
