What is the length of a straight side of either of the last two images.
The original coin (disregarding the denomination and the year in the pic below) looked like this:

about an inch and a half the other alittle less then an inch

If the diameter is 28mm then the coin was, originally, a 2R, if 34mm then a 4R; and if 40mm, then an 8R.

The second one is a British George 2nd Halfpenny, very little value due to it's condition.
