Would like to propose the idea of having coins drop throughout the world that we can collect and trade. They can be of different level conditions - poor, good, fine and mint. They can be made of copper, silver and gold with different inscriptions on them - ESO lore wise of course with past emperors heads on them with something historical on the reverse. Could have coin albums to purchase (from the crown store perhaps) to hold the coins in a collection. And for those who don't want to collect can sell to a vendor for gold.
Being a coin collector myself this would certainly add more enjoyment playing the game.
