Need help with my first exposure to China Empire coins

Here is my first acquisition of China Empire coins. I tried identifying them myself but would appreciate any help from the experts verifying my conclusions as well as helping with those I failed on.

The whole group 1 (1-A to 1-H) is 乾隆 Qiánlóng 1735-1796, all 8 seem to be from ᠪᠣᠣ ᠴᡳᠣᠸᠠᠨ Boo Ciowan Beijing Mint. Why 1-A and 1-E look quite different from the other 6?

2-A is same - 乾隆 Qiánlóng 1735-1796 but from ᠪᠣᠣ ᠵᡝ Boo Je Hangzhou mint.

Both 3-A and 3-B are also 乾隆 Qiánlóng 1735-1796 but from ᠪᠣᠣ ᠶᡠᠸᠠᠨ Boo Yuwan Beijing mint.

All 4 coins from group 4 are from 光緒 Guangxù 1875-1908 from ᠪᠣᠣ ᡤᡠᠩ Boo Gung Kunshan mint.

I have no idea what #5 is.

#6 seems to be 乾隆 Qiánlóng 1735-1796 but I can't identify the mint.

Also have no idea for #7.

Why 1-A and 1-E look quite different from the other 6?

It's the difference between copies and genuine coins

Observe the reverse of the 6 copies : characters are thin, the character in "Ciowan" are leaning and more elegant than usual, the left end of "Boo" is too long.
The rim is not distinct, not sharp.
The obverse background is stud, and the second character of Qian is not correct (nor sharp Z nor like a hook)
There are other minor improprieties.

But these are not actual fakes. They were not made to deceive the collector because forgers do know how to make fake coins without these gross errors and then ... it is a lot more difficult to detect that they are fakes These six coins are just amulets, good luck charms somehow.

For the 1A : DH#22.202 (Type-B - round head of boo, slanting head of tong, broad rims, distinct gap between the os of boo) 1740-1745

And the 1E: DH#22.209 (Type-D square head tong, protuding head boo, Qian like a Z - connecting stroke between head and body of tong) - west branch 1761-1767

Finally got some time to figure all these out by myself after getting clues from Frenchlover.

2-A DH#22.349
3-A DH#22.250
3-B DH#22.255
4-* DH#22.1335
5 DH#25.53, C#1.1
6 DH#22.230
7 DH#22.457 (the closest Numista coin page I could find)

Will appreciate though if the local experts in these coins confirm my identification.

​honk honk

2-A
The head of Tong is radical or radical protuding, DH#22.351, 352, 353, 354
So, lets see the reverse where the shape of "Je" is looking like DH#22.351

3-A
It's a braod rim and you see a distinct gap between the Os of Boo
DH#22.251

3-B
There is no protuding head of Boo

4-A is very suspicious. There are machine struck coins.
No defect is allowed.
When you compare to the other coins, you can see that:
On obverse:
- The rim gets no constant width,
- Characters are flattened,
On reverse:
- There is no distict gap in Os of Boo
- The left end of Guang is touching the inner square

6- There is no protuding Boo, the rim is not so broad,
Characters are coarser, Top of Boo well above the hole --> DH#22.222

7- 1 Cash - Jiaqing Boo-chiowan, and for the compass ...

Thanks again Frenchlover!

Цитата3-B There is no protruding head of Boo

Right, missed that. Than it must be DH#22.256

Цитата4-A is very suspicious. There are machine struck coins.
No defect is allowed.
When you compare to the other coins, you can see that:
On obverse:
- The rim gets no constant width,
- Characters are flattened,
On reverse:
- There is no distinct gap in Os of Boo
- The left end of Guang is touching the inner square

Are you saying that 4-A is a fake and the other 3 are genuine? The rim width inconsistency that you're seeing may be a slight shadow from my scanner.

Цитата6- There is no protruding Boo, the rim is not so broad,
Characters are coarser, Top of Boo well above the hole --> DH#22.222

But there is no "left protruding top of ß of long". May it be DH#22.220 than?

Цитата7- 1 Cash - Jiaqing Boo-chiowan, and for the compass ...

Did I get this one right? Just could not find it in the catalog?

3B - is smaller than 3A, I would say type-B: DH#22.251
4A- the major defect is the shape of Boo
6 - There is actually "left protruding top of ß of long" and no vertical stroke at right top of Qian - DH#22.222
7 - 1 Cash - Jiaqing Boo-chiowan, try to find details ...

Thanks a lot again Frenchlover! Still so much to learn here.

Цитата3B - is smaller than 3A, I would say type-B: DH#22.251

As it is smaller, 23.49mm in diameter, shouldn't it be one of 22.254-257 than?

DH#22.254 doesn't get a distinctive gap is the Os of Boo, 255 , 256 and 257 are not small coins.
And what about Jiaqing ?
