Well, good condition CBFD seiled sells for $200 on eBay, and crushed would be harder to sell.
US vertions of Villager sells for $150, Roselina $40, Falcon $35 or so.
While hype is keeping prices up, the only thing that is going to bring the prices down a lot is a reprint, and it looks like none is going to happen any time soon. And Skylanders does not have a brand like Nintendo behind it, Nintendo figures almost always keep value and go nowhere but up.
Are you planning on opening them? KJM is looking for a us Roselina and I have a UK one spare.
