Here's a little explanation I found at the plugable site.
I've also found by changing the photo quality in the settings (the small spoked wheel on top), It will also adjust the zoom a little.
And yes, to take a picture of a dollar or even a half dollar you'll have to experiment and put it on a stack of books or something to fit the entire coin in the frame. I swing the camera around so it hangs over the edge of the stand then put the coins next to the stack of books and I'm ready to go.

The Plugable USB2-MICRO-200X employs a Varifocal Lens which changes the focal plane with the magnification. In this type of design, the maximum magnification is closest to the lens. The clear plastic housing is the perfect length (after removing the plastic lens cap) to lay directly on the specimen or just barely above. Then adjust the focus until it's clear and you'll be at the highest magnification. To lower the magnification you can adjust the microscope stand so the lens is higher off of the specimen and refocus. Basically it works the same as a simple optical microscope.
