The two French IndoChina pieces (round hole) are probably real. They are worth maybe a quarter in that condition.
The cash coin (square hole) is fake. The large bumps in the fields (around the characters) were deliberately added to give the coins a cast look. Genuine coins are only worth a couple dollars, but these "feng shui" copies were sold in bulk for like 5 cents each. They show up in
ebay lots ALL the time.
