I saw some on Ebay selling for $3000.00. My mother used to say, 'That's when two fools meet, one for asking so much and the other for buying'. They are different but Japanese are noted for tricks to cause special effects, not too unlike our big box stores spray painting plants. They use birth control pills to weed poison to radiation to produce weird plants. Once produced, to see if they breed true. I must admit that I am taken in by such tricks. I love the weird types.
