Why is the Pawn the only piece without a hat?

Love the post and comments. Here's something I found at http://www.chesscentral.com/chess-pieces.htm

In early 1849 Nathaniel Cook, Howard Staunton's editor at the Illustrated London Times, designed the Staunton chess set at a time when players were refusing to play with each other's pieces because of the difficulty in distinguishing the various chess pieces. The main patterns prior to the Staunton pattern were the Lund, Merrifield, Calvert, Barleycorn, Selenius and St George patterns. Cook used symbols in their plainest form. The king had a crown, the queen had a coronet, the bishop had a miter, the knight was a horse's head, the rook was a castle, and the pawn was a ball. The horses' heads were based on the Elgin Marbles. These were designs found in the Parthenon frieze and taken to England by Thoms Bruce, 7th Lord of Elgin, in 1806. The pawns were developed from the freemason's square and compass. Every symbol was supported on a plain stem rising from a heavy, wide base which gave stability. The design so impressed John Jaques, leading wood carver, that he immediately suggested making the pieces on a commercial basis.

At least the pawns are members of some pseudo cult.
