Three more Qing Dynasty Coins

I found 3 more China coins/tokens. I think they are fakes like the previous two that I posted a couple days ago. Just posting to double check before I toss them into my junk pile. All 3 are non-magnetic, 30 grams, and 45.2mm.

Also, for my learning, are all 1-teal silver China coins 100% silver? If a China coin sticks to a magnet, can I say for sure that it's a fake with no silver content at all.
