The question I saw was how to respwn after player dies, not layout reset, but that's just as easy, use global variables, an array of coins with giving them an index on the coin with visible state, on load layout, simply look at the saved state, look at the array, walk it on layout load and show/hide which coins you want.
That's a different question from OP
Another point is this, why reload layout unless your totally wanting to trigger layout load again?
If your simply wanting to reset player and keep state of game, move player after death back to start of level, and simply reset visible on all coin objects. Only reload layout if you need to trigger on layout load
