Hello and welcome.

While we'd like to be more enthusiastic about your coins, I'm afraid I have to report that they are all Chinese-made replicas and fantasies. We have seen them all on the forum before.
Top left: we've seen one of these just recently, in
this thread. It's a copy of an unofficial pattern.
Top centre: the presence of an American
Trade dollar amongst a bunch of other coins known to be fake makes me assume this one is fake as well. Plus, the edge looks wrong.
Top right and bottom right: Having one genuine scarce Chinese coin would be unusual enough, having two identical examples is just plain impossible. This particular Kiangnan dollar fake, with the central Manchu inscriptions missing, is
well documented. Compare it with the genuine examples in
this thread.
Bottom left: The "Maxxico" coin is a complete fantasy, based on a bizarre mixture of American and Mexican coinage design elements.
This old thread was our first encounter with one.
