Hello guys, i was reading this thread, thought i might chip in some of my thinking for the version 1 values.
Okie, as you know all version one requires removeal of the legs to transform from valkyrie to battleroid, and also it's hardly stable because of the weight distribution. Though it's made of diecast, it's unlike the bandai chunky monkey which is perfect transformation but not close to anime. And at that time, it's the best thing we got for the macross.
But considering the price for the 1/60 PT VFs, and the price then, i figure people would sell off their ver 1.0 to fund for ver 2.0
And with the chunky monkey to compete on diecast and transformation, of cos the value will drop.
Of sentimental value, i think the chunky monkey would represent the toys we have in the 80s! Yamato's 1/60 ver 1.0 is sort of like a mixture of both 1/48+ chunky monkey, but of cos more anime like. So with the new devolopement, i think the 1/60 ver 1.0 would really drop in value, further more with the ver 2.0 PT, unless the ver 1.0 is dirt cheap, we can't expect value to go up, when a improved version with PT is out.
Thus to conclude, i think Ver 1.0 might not maintain any collectors value..
1/48, i think will at least maintain some value, but 1/60 ver 1.0 is hard to maintain its value consider all the pros & cons.
