3 Large (Silver?) Chinese Coins

I got these 3 today at a flea market. I'd like to know whether they're counterfits, and (if they are) what thay are (counterfits of). The only one I've seen on the numista listing is the one on the left: https://en.numista.com/catalogue/pieces21231.html





Update: All three are magnetic, but I'd still like to know more about the specific designs.

For the left coin, I'm guessing I'm in this situation:

And somebody's making pendents of the right coin:

I still cannot find pictures of the middle one online.

They're all fake, not real coins, some guy saw some pattern/fantasy designs and thought "yo I'll make fakes outta these"
