That's a good indication right there.
To illustrate: You won't find many Super Blacks for sale either. Last year, Super Cinnys were going for 3,500 on KS (the whole 1 or 2 that I saw for sale anyways)... when the available animals group is that small the seller sets the price- it's not really a "market price" since the availability is limited. Most folks producing these are hanging onto them.
Hope this helps.
