(2nd Post of my day..)

Next odd question for my day:
Being an avid fan of steampunk, a while back I got the Limited Edition run of SJG's "Steampunk".. (numbered and signed)

Later, I discovered that there was a very very very small run of the Limited Edition supplement to Steampunk titled "Steam-Tech".
(Approx. 14) - numbered and signed.

SJG eventually sold off 'proof copies' (around 5 or so) via eBay.

What I'm trying to figure out is whether the proof copy I have is as valuable as the numbered and signed copies or less valuable or more valuable..

Thoughts anyone?
