I really don't have anything special in my collection.. I think.
LPs/EPs:
Little blue men - Jedi Smurf/Blah Blah Machine
Elysium - Celestial sounds and neurotic tribal beats (on 4LPs with a different cover than the CD version)
D.P.O.D - Panza EP (donno how uncommon this one is tho, but I love it tho! )
CDs:
Hallucinogen - Twisted (Dragonfly print)
MWNN - Moment of truth
X-dream - We created our own happiness
tho, I think these are pretty common, but they are the most "old gold" CDs I have
