Nope they didn't people think that Banana are fairly new and drop very fast when in fact they are not and did not drop faster than spider, pinstripe or Mojave people just think they do because they were not as involved or paying attention to the market a decade ago.
(Back in 2007 (9 years ago) Banana were in Daytona with a price tag of $60000, yes their priced dropped like any other dom and co-dom but it actually dropped slower because originally only females were produced and released. It's only when male makers were produced and more pre-dominant on the market (around 5 years ago) that price started to drop significantly (just a simple supply and demand thing).
