1 Cash -
Kangxi Boo-chiowan
The bottom part of the 'Xi' is odd, and looks like the Lo-han cash, but:
- there is a seven stroke 'bei',
- it seems smaller than a Lo-han cash,
- it's a 1 dot 'tong'
- and the left straight part of the 'Xi' looks different.
So 4 differences is enough, I let you juge ...
The two other coins are an evocation of
Yongzheng Boo-chiowan
The manufacturer added small dots in order not to confuse them with genuine coins
