What has a head, a tail, is brown

Riddle: What has a head, a tail, is brown, and has no legs?

Answer: A Penny. (a coin)

Hint: Think small, round, and in your pocket.

Why this answer works
Coins have a “head” (obverse) and “tail” (reverse). A penny is brownish (copper-toned) and, of course, has no legs.

Fun fact
U.S. pennies were mostly copper until 1982; modern ones are zinc with a thin copper plating.

FAQ
Is “coin” acceptable?
Yes—the classic answer is “penny,” but “coin” fits the clues.
Why not “worm”?
A worm has no legs and can be brown, but it doesn’t have a distinct “head and tail” in the coin sense the riddle plays on.
