This is the only Ace that doesn’t depict any Yod, indicating it is a card of the material and mundane plane. This is the beginning of finding our feet. We have spent time developing our emotions, our energy and our intellect, and now we must participate in the physical world. This is the beginnings of that development.
Having spent your time with the Ace of Swords, the Ace of Cups, the Ace of Wands, you have the passion, the know-how, the love to bring into fruition a physical product. On each coin is a five-pointed star. While it might seem that Earth is the lesser of the elements since it represents a more base learning, it is the physical representation of the other elements coming together.
