Since I began to get serious about koi, there have been a lot of 'hot topics' of the day that come and go. One constant has been questions about whether the price of a koi is fair. A photo will be posted and the poster will write 'It was bred by so-and-so. The price is $XXX. Is that a good price?' I often say that price is a matter of opinion. A koi is worth a certain amount if the buyer believes it will give them enjoyment worth that amount. Most of the time, however, the person asking the question has no idea at all. They know that they do not know enough to tell whether the price is fair, high, grossly overpriced or a bargain. They know they do not know enough to tell whether the koi will be one they still think is pretty a year later.
Koi are one of those rare commodities which are purchased most of the time by folks who have little or no knowledge of whether they are paying a fair price. I would guess that 99% of purchasers consider the price being asked as the mark of the quality of the koi being offered. Take a random netting of Kohaku and place them in a dealer's sales tanks priced at $50, $100 and $500. Ask folks to choose the best koi, and they will look only at the $500 ones. It is assumed the dealer marked the prices according to the quality and potential of the fish. This example may be extreme, but every day there is a posting on Facebook by one dealer or another of a 'special' koi from a name breeder. How many people can say that koi is worth $2,000 or $6,000? ...I would suggest that even among most experienced koikeepers, very few know enough about what they are seeing to be able to place a 'fair price' on a koi. They may well see that one is an inexpensive Chagoi, but is it $25, $50, $75 or $185?? Is the nisai Shiro Utsuri fairly priced at $1500? Would it be a bargain with a 30% discount... $1,050?
When buying a car, people will test drive, compare prices, compare the extras added and decide what fits their needs. Maybe a Lexus is right for them, or maybe a Toyota truck with just the basic equipment. With koi, we really do not know what we are getting. Even the most experienced are imperfect in their predictions of future development. Will the sumi actually become the intense black we think it might? Will it grow as long as we hope it will? The more experience a person has, the more likely their hopes for the future will come true, and therefore the more likely the price paid will be fair for the enjoyment they get from the fish.
We like to think that market forces will assure that the prices we pay will fall in some reasonable range. But, relying on the market is not a wise thing to do when many market participants are not knowledgeable. And, some are not ethical. Ray Jordan often told a story about his education concerning koi pricing. A dealer told him that a particular koi variety was more expensive because it was produced by a big name breeder known for the variety. Ray later learned that breeder did not breed that variety and never had. All you have to do is look at the pricing of koi on Ebay. A lot of $20 tosai sold in bulk get listed as 'rare' and priced at hundreds of dollars.
Probably the fairest prices are those paid in Japan by dealers to the breeders. I say that because those transactions involve the most knowledgeable participants overall. To cover expenses and make a living, the dealer will need to mark-up his prices by at least 50% and usually more like 100-300% on individually priced koi, and perhaps 600-800% on bulk tosai. A hundred little tosai sold to a dealer for $700 become $50 each in the sale tank. A big mark-up, but likely producing little profit for the time that must be spent to sell them and the cost of maintaining them. If the dealer sells them for $100 each, he may do pretty good profit-wise, but it still does not amount to a lot after paying the rent and electric bills. But, a customer who learns they paid $100 for a $7 koi is not going to be happy about returning to that dealer.
The best purchase I ever made was a group of 4 tosai Showa that cost me $40 each. I got them from Mat McCann and had the fun of watching them grow over the summer. They were worth their cost just for that experience. Three were re-homed and one I kept for another year. She is still in my pond. When she was 3 or 4 years old, she won a Best Showa award at CFKS. Her sumi remains intensely black to this day. Her beni is showing its age when viewed up close, but in the pond is bright red. She is still a pretty fish and has given a lot of enjoyment. There have been other koi that cost much more and gave less. I wish I could say I made a brilliant selection when I got that Showa. It was, but it was luck. The other three did not stay a full year.
So, I say the real value is in the enjoyment received. And, that is a matter of personal opinion. But, knowing which koi will give that enjoyment requires more than knowing what you like.
