Three brass coins, square-holed in the old cash-coin pattern, each face stamped with characters on one side and left plain on the other. They sit in a small drawstring pouch alongside a paperback translation of the I Ching, its pages numbered to the sixty-four hexagrams the coins are cast to build, one line at a time.
The I Ching, or Book of Changes, is among the oldest of the Chinese divination texts, traditionally consulted by casting yarrow stalks or, in the simpler method this set follows, three coins tossed together six times over. By old custom, the mix of heads and tails in each throw builds one line of a hexagram from the bottom up, and the finished six-line figure is looked up in the text for its reading.
These coins are cast in brass rather than stamped from sheet metal, giving them a heft closer to genuine antique cash coins than the thin reproductions sold as souvenirs. The included translation favors plain, literal wording over the more poetic renderings common in older editions, chosen so a first-time reader is not left guessing at metaphor on top of the method itself.
Toss all three coins together, note the pattern, and repeat five more times to build the hexagram from bottom to top before consulting the book. Slower and more deliberate than a card draw, and better suited to a question that deserves that kind of patience. A method that rewards sitting with the answer.
