Until now I had never heard of Blake and Company. I don't know the value of that coin. The first thing that you need to do is verify its authenticity. See if its magnetic (it shouldn't be), weigh it, Here is some text that I found about the company. After doing some research I have been unable to find the value of the coin. Your best bet is to bring it by a coin dealer. If they think that its real than send it to a grading company to have it authenticated and graded. I can't really tell you much more than that.
