As posts from boldlygo, Alindawyl and thewanderer noted,*** I would like to emphasize that Tarot cards were not originally intended for use in fortune telling, but for card games***. So there are purposes for tarot cards beyond what is commonly thought for them in English-speaking countries.
I was responding to a specific post from a specific poster about a specific situation. That situation was a student from France who had a deck of cards for playing a game called Jeu de Tarot, which they played for an evening and did not, in his words, “sprout horns”. I only wanted to point out to him why someone would treat a deck of Tarot cards as a game rather than a tool for divination.
Are the Tarot cards you have designed for gaming? Were they given to you by a Frenchman, or some other continental European, after playing a trick-taking game with them? Do their box and the cards themselves look like this:
Tarot cards for playing Jeu de Tarot
If the cards you have resemble this, then they are designed for playing a game and nothing more. They are clearly similar to a standard deck of 52 cards with some additions. There is an extra face card in each suit (the chevalier) between the jack and queen. What we call the jack they call the valet. There are 21 trump cards and the fool. But the trump are simply numbered. The pictures on the trump of a gaming deck are rather innocuous depictions of ordinary things. The face cards have a face in the similar style of the jack, queen, and king of a standard deck of playing cards. The four suits are the standard French suits that are in use by most of the world (clubs, diamonds, hearts, spades). The numbers and letters are in the corners to facilitate easy determination of each card’s value when held fanned in the hand for playing a game.
You may sell such a deck with no worries. No one uses them for divination.
But I doubt that’s the kind of deck you have, as they are extremely rare in English-speaking countries. This is probably the general style of what the Tarot cards you own, and are most likely to see in English-speaking countries, look like:
Tarot cards for divination
These cards are quite clearly different. Each card, from the trump down to the most basic suit card, has been given a very specific occult meaning. The trump are all named rather than simply being numbered, and usually they aren’t even numbered any longer. All cards have pictures on them. The trump are no longer called trump but “major arcana”. The suits are not the French suits, but are either an exact transfer of the suits originally used in Italy (cups, coins, clubs, swords), or more frequently some variation of those suits. The most common variation is to replace clubs with wands, because wands are associated with magic and clubs are not. The cards are not designed to be held fanned in the hand, so have no letter/number in the corner.
The occult connotations of everything about such a deck are blindingly obvious. Just as no one uses the former deck for divination, no one uses the latter deck for gaming. Looking at them side by side, you can understand the reaction of my French Exchange partner when I asked him if anyone used the gaming deck for fortune telling. The idea was as preposterous to him as the family gathering for dinner, sitting on the table, and putting their plates on their chairs. I mean, you COULD do that if you really want to. But who would unless they were being deliberately contrary or were insane?
All of that aside, you should never treat anything related to the occult as being of no consequence. It’s best to destroy them. Not out of fear, but out of practicality. You don’t want to keep those kind of Tarot cards for yourself, and you certainly don’t want to possibly participate in the sins of others by selling or even giving away an item designed specifically for occult purposes. Destroying them is the most practical way of disposing of them.
