NIP
hmmmmm, there are different ideas about collecting and maintaining condition.
there, surely, is room for all methods.
I am a slot car guy and I deal with different causes regarding originality going back into the late 50's.
yes, un-played with toys are worth more if you can find someone wanting one bad enough.
however, trying to sell a collection for it's imagined worth as NIP never occurs.
investing in toys as a retirement fund is not going to work.
personally, I drill the "rivet" off the bottom and use the die cast bodies to make masters for resin slot car bodies.
in closing,
for purists .... every time someone opens a NIP toy, yours gets a little more valuable.
