Don't hide your coins away. Display them where everyone can see them. A Coin Tie Pin is a great way to display an interesting coin, and is a fine conversation starter.
A popular coin to top a tie pin is a Spanish, or Spanish Colonial, Half Esudo gold coin. This small coin is the gold equivalent of the silver Dollar or Peso. This example has a coin of Charles III of Spain minted in Madrid in 1786.
