Is my Coro bracelet worth anything?

Tweet

I just bought this charm bracelet from a thrift store the other day and I found that it said Coro on it, so I looked it up on google. I didn't really find anything on it, but I found out it's from the '70s to '80s and I found another bracelet that was supposedly worth about $30. It has 4 charms that I believe originally came on the chain and then 4 beads that I think were probably added later. So I was just wondering if anyone could tell me about how much mine would be worth or if there is any way I could find out for sure. I am posting a picture of it, but my camera isn't that good, so you can't really see it all that well.
