Calico Cats are Rarely Male.
Calico cats are almost always female. This is because the gene that codes for coloration is found on the X chromosome. This 'color gene' will code for a specific color such as black, orange, etc.
Each individual receives an X chromosome from its mother. It receives a Y (male) or X (female) chromosome from its father. Female kittens, then, have 2 X chromosomes and males have a Y and an X.
A cat must have 2 X chromosomes for it to be calico. It takes 2 X chromosomes to be female; and it takes 2 X chromosomes each carrying a gene that codes for a different color for the cat to be calico. Another chromosome (not the X or the Y) codes for white.
As the early embryo develops, some cells turn on one X chromosome, and some use the coding from the other. Let us say cell A turns on the X chromosome whose 'color gene' codes for orange. As cell A divides, all its daughter cells will also code for orange. This results in a patch of orange, since the daughter cells remain in a group. Another cell, cell B, turns on the other X chromosome which happens to have the code for black. Its group of daughter cells will result in a patch of black. Because the early embryonic cells randomly turn on one X chromosome or the other, we get these multiple patches of color.
There are rare instances when a male kitten could have 2 X chromosomes and one Y chromosome. He then could be a calico if each of the X chromosomes has a 'color gene' which codes for a different color.

Male Calico can't be tomcats because they are mostly sterile. And they are rare because they carry an extra X chromosome. Approximately 1-3,000 calico's are male & out of those only 1-10,000 are fertile. The biggest myth is that because they are rare, they are valuable and can be sold for a lot of money. You may be able to find someone who is willing to pay for such a cat, but no one doing a pedigreed breeding program of any breed should be willing to use such a cat in their breeding program. There is also a long-standing myth that if an owner takes a calico cat to be spayed and it turns out to be a male calico which the vet then castrates, the owner is entitled to get the money back from the vet for an unnecessary neutering. This isn't true - even though the male calico is likely to be sterile, he probably still has the male hormones which make him spray. And if people do pay a huge amount of money for male calico, how do you explain the numbers of male calico residing in shelters around the country? Surely if they are worth much, they won't be abandoned and homeless.

No, there's a number of male calicos, they only are 'rare' because they don't have that coat pattern very often--it's sex linked by genes to the female cats. Most male calicos are sterile (can't reproduce) which saves you on getting them fixed I suppose, but no, just being a male calico won't get you any money.

There are no male calico cats. Calico describes a distinct color pattern involving the colors orange, white, and black. Calicos are always female.Some people believe that calico cats are a breed, or that calico refers to a color of a cat. Since all cats are colored, calico refers to the pattern of how the coloring appears on the cat's coat.
According to a leading expert in Feline Genetics, Dr. Elizabeth A. Oltenacu of the Department of Animal Science at Cornell University:
"Early in its inception, a calico/tortie kitty is formed by a gene known as the white spotting factor. The white spotting factor effectively slows down the migration of cells across the kitten's body. One X-chromosome in every cell is switched off.
This is a random happenstance, and when a tortoiseshell kitten appears in the litter, you will see a mix of two colors of hair on the kitten.
In a calico kitten, the white spotting factor being present allows patches of cells with the same X chromosome shut-off to develop.
The results are patches of white, orange, and non-orange in the kitten. The more white in a calico, the larger the patches of white, orange and non-orange because the migration of cells in the embryo is slowed. Once the color is in patches, you can see the effect of the tabby genes in the orange patches."
Calico cats are overwhelmingly female. According to The Cat Fancier's Association Complete Cat Book; Persian calico cats have been accepted by CFA for years and calico Persians are always female and give birth to black-and-white or red and white bi-colored sons.
Genetically, two X chromosomes are needed to produce a calico coat, which is why the majority of calico cats are females. If the colors are black/orange upon the coat, then the cat is a calico cat. If the colors are blue/cream instead of the standard black/orange, then the cat is a muted calico
It has to be female, as this requires 2 X-chromosomes. Sometimes an abnormal male is born XXY instead of the usual XY, so can be tortie, but not calico.

Not worth any more then any other color cat. Yes they are rare, but most all male torties/calicos will be sterile and not breedable. I do know of 2 male calico breeding Cornish Rexes (personally seen both) and know they have sired kittens. The one is owned by a good friend of mine. She recently discovered that her male calico is passing on this oddity to grandchildren - she has a lavender-cream male kitten she is keeping.

Yes they are rare but I don't think that they are worth $500. I got a male calico at a shelter for the same price as other cats!!!!!!

There's no such thing as a 'male' calico cat. The gene for the calico coloring is a sex linked recessive. In other word it's only on the X chromosome, and in order for the color to be expressed you need two X chromosomes. Not an XY.
If you do find a calico that seems to show male characteristics it is probably an XXY and would be sterile.

Male calicos are extremely rare but I don't know that they are worth any money. They are not a breed, calico simply describes a color pattern.
