I wish I had 30 tetradrachms! This is my favorite coin in history. I'm an Athenian and I have been inside the very mine those were produced! I wish I had one! Those coins were (in my opinion) the best silver coins of the ancient world. If anyone could give me the 330 BTC I need to buy one, I would appreciate it! 30 of these half ounce coins were given to Judas to betray Christ and even though I'm an atheist I find that number to be the one where you have a significant amount of silver. Imagine the implication of holding 30 tetradrachms in your hands.
