The Megalithic Money of Yap
The tiny island of Yap in the western Pacific holds a strange attraction for economists, because it cuts to the heart of a very basic question “what is money?”
For centuries the Yap islanders have used huge megalithic crystal discs as their money. Shaped like gigantic wheels and carved from single blocks of calcite crystal this ‘stone money’ is called “rai”. The largest yet discovered measures 12 feet in diameter (3.6 meters) and weighs 4 metric tons, the weight of four family cars, a truly unique form of currency.
The rai stones were not used for just any purchase; day-to-day commerce was conducted with the exchange of shells, necklaces, baskets of fruit and cups of syrup. The rai were special, reserved for things like a bride’s dowry or exchanged when one tribe came to the aid of another in times of war and hardship.
Exactly how the relative value of each rai stone was calculated is still a mystery, but we do know that they were considered extremely valuable. A small rai stone was enough to buy some livestock whereas a large stone would be enough to buy many villages and plantations.

The size and craftsmanship of the crystals give only a rough indication of their value. Far more important to the value of the stones was their ‘story’.
On Yap, there is no source of calcite crystal for making rai stones. Archeologists have discovered that, beginning around 500 A.D., the megalithic stones were brought to Yap from the ancient crystal mines on the island of Palau, more than 280 miles away. The stones were quarried, shaped and then shipped across the open sea; a journey that took more than a month. Each stone arrived on Yap with a ‘story’ of its intrepid journey. The stones that endured the greatest dangers were valued most highly.
Rai stones could even earn ‘interest’. Increasing in value according to the good deeds and successful partnerships they were used to finance. For example, if a stone was used as a dowry and the marriage was good, resulting in many children of good character, then the value of the stone increased accordingly.
According to local legend, one of the most valuable rai stones was lost at sea in a great storm and never even made it to Yap. The huge crystal now lies at the bottom of the Pacific, 100 miles short of its destination. The islanders agreed that this particular rai stone was now of great value, even if they couldn’t set eyes on it.
Due to the huge size, terrific weight and the great difficulty involved in moving the crystals, once in place on the island (or at the bottom of the sea), the rai stones stayed put and the megalithic currency quickly made the leap into something very abstract.
Imagine, if you will, in the middle of the village is a huge round crystal rai stone. One day the crystal belongs to me, then you and I engage in trade and the next day the crystal belongs to you. But the stone never moved, no unit of currency changed hands, just that everyone now knows the stone money belongs to you.
The concept of Yap’s ancient and abstract stone money system somehow feels strangely ’modern’. When you go online to pay a bill, what really changes? A few digits in a computer at your bank and a few digits in a computer at the other end, but no ‘thing’ is exchanged, no ‘stone’ moves.

Yes, these round stones containing crystals also remind me of the Dropa Stones that were found in a cave in the high mountains of China. Even modern and 19th century Chinese money is round and has the characteristic hole in the middle although the ones I have seen and found while metal detecting at old Chinese mining sites here in the western USA have square and not round holes in them. Interesting history though. This round shape with the holes in the middle and often a notch on one side, like the Dropa Stones ( and even many UFO's! ) is rather common all over the world when we look at almost all very ancient cultures. There must be more to it than we have caught on to as of yet. This is why I love history and am fascinated by all ancient cultures. Especially the Polynesian cultures, etc. that settled the Pacific. It's quite obvious that they sailed their huge canoes and boats all the way to North, Central and especially South America far, far back in time. The evidence is there for all to see. Easter Island being one example. It's in the middle of nowhere yet it was found and settled. The huge statues there are so similar to some found on the South American continent. Curiouser and curiouser.........
these things remind me ancient chinese disks. their purpose were unexplained. maybe they used like yap stones.
Tigress, thank you so much for your very interesting and insightful comment about calcite crystal.
One thing I know about calcite is that it is found at every single ancient temple and pyramid site in Egypt. I even brought some home the last time I was there : ).
Thanks for the new information.
All the best.
I see what you mean.
Money has always been a difficult subject for me to get my head around.
'Value' and 'worth' on the other hand, I can understand. But money? That's a real tough one.
Money means freedom/ power/ control if you have it and constrain/ struggle/ subjugation if you don't. I say that without any political agenda, just as an observation.
And all the time, the very 'thing', the money itself, has no inherent value what so ever. It is like we are 'praying at the pulpit' of a false master and it only works when we all play along.
Like I said, I struggle with the concept of money : )
Thanks for sharing your point of view.
