Yes. Well not so much a coin as a proposed coin. Although there is no documentation it is believed that these were a proposed coinage to replace the one dollar note in the continental currency issues. (until the 1776 issue the continental currency notes had included a one dollar note. The first? 1776 issue did not have one, not did the next couple of issues. Then the one dollar note returned around I believe some time in 1778.) These coins have been copied probably since the start of the 19th century and there were a lot of copies made around the centennial in 1876. There have also been a lot of copies made during the 20th century. Before the passing of the Hobby Protection Act in 1973 many of the copies were not marked. Since then most are marked but each manufacturer marked them in whatever location they chose, there is no standardization of marking location. Most of the copies are of poor quality, usually cast with rough surfaces, very few are die struck like the originals, and most of the die struck copies are not in the same materials as the originals. There are some deceptive copies, typically not marked, and many of them were probably from the 1876 centennial. Also most of the copies are not of proper weight. I can't say when this copy was made. It could be from any time from the mid thirties to last year.
The fourth image looks like the casting port. You really should kept it as a study piece. The day may come when we'll be better off trusting ourselves.
Can't be sure, but with the way the word COPY looks I would strongly suspect this is a post 1973 copy. The Continental Currency dollars can be found in the 2014 Redbook on Page 85. Should be close to that on other editions.
