for a legendary they are pretty easy to get - they should be WAY harder to get and then they would have some value - like the shinies for example if they were 1/4k they would worth 25/50k per shiny - lowest shiny is probably around 900k because of the odds
good luck they are hard to sell - people want good 2012 pokemon for same price as today pokemons - i would recommand to be patient and dont sell for cheap
