I couldn't care less. I traded most of my doubles away already and i can't say i'll shed a tear over it. I got some good deals on my vintage camera beards/medic masks but i wont fret on what i could have got later down the line in TF2's dying moments.
People put way to much interest in digital equity already. This stuff doesn't exist and isn't useful, cannot be legally traded for wealth and subsequebtly of no consequence.
EDIT: Also, as with all collectable items, the value is subjective. Just because someone baught an original winnie-the-poo bear doll from 1926 for 2 million pounds doesn't mean that anyone else gives a shit and/or make its base value to anyone else that amount.
