Take a piece of paper and cut out a perfect circle with diameter 1 inch.
What is the diameter of the largest unaltered coin which may be passed through the hole without tearing it?
(Consider the coin to be very thin, and the paper to be very flexible and tear resistant, but not at all stretchy.)
(In reply to re(2): My 2 cents worth
Richard I tried it out practically by cutting a paper and found this is possible. I am not sure about the stretchy nature of the paper used. Thinner the ring width easier for the paper to form an almost straight line.
