Two of Coins
Coins are often taken to represent wealth, intellectual (said to be the more important) as well as material. They are sometimes called 'Pentacles' through a translation error.
The Two of Coins in the Marseilles deck is unusual in that it shows the two coins bound together, perhaps representing close ties of friendship or love.
Maybe it should be the patron card of Computing since it is shows the binary dialectic: true, false; yes, no; love, hate.
Or perhaps the two circles are names, and the card represents a fusion of names. This is the subject of my Computer Science research.
