The condition of bust dimes directly affects its worth, so keep that in mind when adding to your collection. A high-quality example of a coin is often worth many times as much as a poor example, although there are always exceptions to this general rule. Of course older coins are generally more valuable to collectors, but more than just age can affect the value of a specific coin. While age and rarity are important factors when determining the value of a coin there are other factors that affect the coin's value in the eyes of a collector. Demand is a key factor in the market value of any collectible coin.
