Two Chinese Cash Coins - Identification?

Found these two cash coins in a world coin bin for 20 cents each. Anyone here able to identify them? I don't know anything about Chinese coins, I just think these are Qing Dynasty.

Interesting that one appears to be copper while the other looks more like brass.

Looks like the "brass" one is..

Chia-ch'ing
1796-1820

The copper...

Chien-lung
Qianlong 1736-1795

 

I looked on an identification site. I got these results too.

Not in the best of shape, but for 20 US cents each, I'm happy to own them.

 

That's all that ever really matters to me.

 

FYI - They should be rotated clock wise a quarter turn each to be the correct orientation.
