The first coin is a copy of 1 cash Jingyou YB (too much precise to be genuine for a coin supposed to be a millenium old)
The last is from Jiaqing Boo-Yuwan
This is not true, the Jingyou is absolutely genuine.
It’s been cleaned using acid, which gives it a specific surface look, but it’s real. Chinese cash more than twice as old as this one can look even better, just because a coin is in good condition doesn’t mean it’s fake.
