This thread has started out really nicely!
The first thing that came to my mind was that it would be useful to discuss a little what threes mean. Twos were easy - duality, and all that stuff. Threes are a little more complex. I will just discuss one aspect here:
A three forms the first geometrical figure. The triangle. A triangle normally points up, or down (and sometimes sideways, but that is more rare). So if it points up, it's pointing to the spiritual or the mental realms. If it's pointing down, it's pointing to the material or the earth realms. (Well, at least that's my take.)
So if we look at the Three of Coins and Three of Cups, the triangle is pointing up. In the Three of Batons, there is a triangle pointing both ways. In the Three of Swords, goodness me, there isn't a triangle. Uh-oh.
(It can also be useful to note that the third cup, baton and sword seem to have grown out of the central flowers of the two's. But where on earth did the third coin come from? Note that the Two of Coins, in the Grimaud deck, has a touch of green - very unusual for the minors.)
So from the position of the triangles, can we safely say that when the cards are read upright, the Three of Coins and the Three of Cups allow us to connect well with the Mental realms? Of course, this is wonderful for the Three of Coins, because as it's an Earth element, this provides tremendous stability. There is no more hesitation, as in the 2s, or vacillating between the spiritual and the material. Here the Three of Coins has the best of both worlds.
The Three allied with the Water element, i.e. Cups, really reinforces all matters of the heart and emotions. But where is the grounding here? A very emotional card this one is. Almost euphoric. A little unstable at times. Could point to some immaturity or inexperience in the matters of the heart.
Two triangles for the three of Batons. What more do you want? Stop complaining and get on with it, this card is ordering you. That middle Baton really holds the whole thing together. It's almost like a sceptre - gives one great power. There is not need for hurry or confusion. All is clear and nothing stands in your path. As Rusty Neon pointed out, the Batons are slightly thicker here too. An important thing to remember. This is a great card when one is wanting to start up a new activity (when it's upright, I mean).
And now our three of Swords. Poor little card - no triangle. Does it matter? Not one little bit! Three's are spirit itself. (The Christians talk about the Father, the Son and the Holy Ghost.) So if you have Spirit allied with Spiritual things, what more can you ask for? (Oh, but if it is reversed, what a calamities it can bring....
).
(You see, this is where I have big problems with the Rider Waite and clones' 3 of Swords. It gives a picture of calamity - only one side to the picture - a heart with three swords stuck into it - what melodrama! But where is the Spirit in Spirit? The Great Unity? Nowhere, nulle part, nirgends........ but that is another story, one that, as many of you know, gives me sleepless nights
