Three boxes are all labeled incorrectly, but you must determine their contents, nevertheless.
The labels on the boxes read as follows:
[box 1] gold coins
[box 2] silver coins
[box 3] gold coins or silver coins
To gain the information you need to determine the contents of each box,
you may remove a single item from one of the boxes. You may not look
into the boxes, nor pick them up and shake them, etc.
Can this be done? If so, how? If not, why not?
Wait. That was the old puzzle.
The rules have been changed.
You can't open any of the boxes.
You can't remove any item from any of the boxes.
You can't even touch any of the boxes.
You're also told that the boxes all contain coins of a single type: gold, silver or bronze.
No two of the boxes have the same contents.
