Silver Coins

Info
Silver coins are the third most valuable coin in Terraria. It can be crafted by hand with 100 copper coins, or it can be looted from enemies. It can also be found in smashable vases, chests, Treasure and Goodie bags, crates, Angler's Quest Rewards, or by selling something you own to a Town NPC. When you gather 100 silver coins, you can make a gold coin by hand.

Not only can it be used for buying equipment from Town NPCs, it can be used as a ranged weapon. It does 50 damage, and can be used as ammunition in the Coin Gun, or on its own as a throwable weapon. Silver Coins cannot be retrieved when thrown or fired.
