The I Ching or Book of Changes is an ancient Chinese divination manual and book of wisdom. Especially since the 1960s, its poetic text and extraordinary symbolism - to say nothing of its strange effectiveness in divination - have gained it a following in the West. These I Ching Coins are replicas of ancient Chinese coins, engraved with Chinese characters, perfect for casting the I Ching or for use in divination or for Feng Shui. Each has a square opening which allows a string or ribbon to pass through. They come in a pack of 6 or in a bulk package of 100.
