3 Chinese ? Coins Help

I know next to nothing about these, but I do know they are one of the most counterfeited coins on the planet.

I'm back! All three are the same. If you take #1 and turn it 90° CW (to right 1/4 turn) that is the alignment. The left and right characters represent the dynasty, the upper is the Emporer lower has something to do with the reign, can't remember. The reverse, the squiggly character is left means Board of Revenue mint (Chinese script), right symbol means Fountainhead of Currency (Manchurian script)

Now as to copied. These are cast brass, one of the easiest to replicate. Originally they were cast in the branch form, like a tree, coins were leaves on a stem. The workers would break them off and file the rough spots off. I think that's on coin #3. Is it real or is it Memorex? I can't tell, I do suspect they may be real due to the wear on the characters, making them thick. You may want to check this out further if your interested by googling "Ching dynasty coins". The original coins iv VF condition are only worth $3, no high $ stuff here, just interesting.

The left and right characters are tongbao and have nothing to do with the dynasty. Tongbao is more or less: "currency; coin; report; information; bulletin; dispatch; message" (according to direct translation) and was the currency name of most of the cash coins from China and nearly all of the Korean coins from that period. Korean uses tongbo for example.

The top AND bottom characters are the emperor's name, in this case Chien Lung or Qian Long. https://en.wikipedia.org/wiki/Qianlong_Emperor

Crazyb0 is correct however, in stating the coins are not right side up.
