1) because feathering creates pixels that are partially selected. The ants march on the 50% selection line, if you have an isolated area where the selection is below 50%, there won't be any ants to show it (but it can be visible with the "quickmask"). Feathering may not be the right technique to get rid of such areas.
2) The Fuzzy selector by design works on contiguous areas, so I don't really understand the question.
Something often overlooked is that the selection applies to all layers, so you can create a selection using one layer to cut another layer. In your case you could duplicate the layer, increase contrast on the copy to make the background almost completely white (as long as you don't create dents in the outline of the coins), make a selection from that, then hide the copy, activate the initial image and cut it with the selection.
But IMHO you would save a lot of time by taking the pictures on a contrasting background (red/green). Then you would be able to use color differences to select things.
