I have two coins.
* One of the coins is a faulty coin having a tail on both sides of it.

(For the purposes of this exercise, thumbs count as fingers, for five fingers per hand.) If you cannot estimate the number then try to guess how long the number would be.

Different lights make me strange by changing me into different sizes. What am I?
