What are the indicators of a fake and the indicators of a real coin...
Here's your picture again, with two things that sent up red flags for me highlighted.

The red arrow points to the denomination mark, "1 tael", which I mentioned earlier. The "tael" is a unit of weight; a 1 tael coin should weigh 35.5 grams, or one and a quarter avoirdupois ounces. I'd be willing to bet your coin weighs much less than this.
The green lines point to the zig-zag-arrow border, which is not seen on Imperial-era coins that were actually issued.
