what's the rarest record you have?

[bryantm3]

mine is moby's first 12" single under the name 'the brotherhood' entitled 'time's up'. but even though this had only around 500-1000 copies, mine is extra special because it's a german test pressing. then last march i went and got it signed by moby, and he told me it was the rarest record he'd ever made:
