COLUMBIA, Tenn. – Visitors to former James K. Polk’s ancestral home today were the first in the Nation to get Presidential $1 Coins bearing his portrait.  The coins were made available following the United States Mint’s ceremony to officially present the coin to the Nation.  To commemorate the event, each child 18 years old and younger received a newly minted James K. Polk Presidential $1 Coin.  Adults at the ceremony exchanged their currency for rolls of the new coin.
