[Dnd] In dungeons and dragons, are gold pieces actually made of gold?
gpt
Yes, they are, but gp are not commonly used, it's more of a sign of a wealth status to use them instead of more common silver and copper coins. If someone says 'I have 3gp on me' it's very rarely in 3 coins, it's more of 20 sp, lot of copper, a button and sock (still useable).  

If you are asking because the gold is rather rare thing to find - it's all about value, not about being literally worth '3gp'.
