The interpretations and symbolism for the three of coins is one of the most consistent I've seen across the various tarot decks and books that I've read. It is almost always some iteration of "creativity and skill"
I was really happy when this card turned up today. I pulled it about half an hour after writing this post for my other Kindle-available blog "The Vampire Diet". In my eyes, it is clear validation of the thoughts in that post. Put simply: It doesn't matter how your creativity and skill compares to other people. The important thing is that you use them - hopefully to the best of your ability to do so.
