Like everything else in this world, coins are subject to the supply and demand system. If the supply of something is small to almost non-existent, even moderate demand causes a shortage. Desire for a certain item (in this case a coin) that has a limited quantity causes the price to go up, as there are not enough to go around. If a greater supply suddenly appears the price could drop, and if demand grows the value goes up.
