Cast Cash help Please

What I think I know:

#1: Jiading- 25mm   - Can't find a listing for plain reverse
#2-4 :no idea- sizes in order    24.25mm(widest point)   25mm   20.75mm
#5-7: copies/fake? sizes   15mm     22.6mm(1.75mm thick)   20mm

Any help is welcome. Thank you

The smallest one is definitely fake.

3&5 fakes, 6&7 modern amulet/charms.

nr 3 original:
av: yong zheng tong bao
rv: boo je

nr 4
av: qian long tong bao
rv: boo chiowan

#3 is a fake? that is disappointing

Verweis : eazy.dognr 4
av: qian long tong bao
rv: boo chiowan

I was afraid of that... I have a bag full of Qian Long that I haven't been able to determine the exact variant.


Literally

Thank you for your help Easy.dog and Kommodore.

I think that you are right bbybugs. Thank you.

good job everyone. Thank you

3 5 6 and 7 are fake

Regarding the Qianlong coins, it's not about the size, it's about the characters. Look for the コand マ radical on 通, and work your way from there.

Yeah. I was assuming 5, 6, and 7 were fake but I didn't expect 3 to be, but I see it now.
Ok. If size isn't a consideration then it should be a little easier. Still a daunting task. That was only a few of the ones I'm working on. It would be great if we had a Numisdoc with a side by side picture comparison (hint hint)  
Thank you Kenny, for the help
