Fake? Hong Kong #3 And #6?

I recently acquired a large lot of Hong Kong stamps and most were identified correctly.
Three were labeled as possible fakes.
I tested all 3 for watermarks and found none.
I looked at a few examples and the Chinese characters look accurate to the untrained eye.
The font on #6 used for the "48" before cents looks odd, but I also saw variation in a few examples on ebay, but maybe these are fakes too.
The perfs on #6 look odd too and the few remaining don't line up very well with 14.
But its hard to tell. Maybe closer to 12 1/2

and then #3's perfs are definitely not 14. The one with measurable perfs is 12 1/2 x 12 1/2
So if the perfs are "wrong"... what are these?
Complete fakes? Made recently or back in 1862?

Scott doesn't mention any variants, or like stamps.

I would appreciate your expertise and opinions.

The three stamps you have scanned in are all forgeries. The most commonly found Hong Kong forged stamps were manufactured by the lithographic firm Spiro Brothers in Hamburg, Germany. The head of the firm was Philip Spiro. In 1864, his company began to produce forgeries of postage stamps of the world with about 500 varieties. They were sold to stamp dealers as "reproductions."

The easiest way to tell they are forgeries is to look at the horizontal background shading lines and see if they touch the vertical frame lines at the left and right. If they touch, they are forgeries. Also, count the shading lines. 73 lines is a forgery.

This is how they were sold, in sheets with cancels printed. This is a partial sheet. (image from ebay, not my forgeries)

Much thanks Linus!
I will take a closer look at the rest of my lot.
