Sequenced Note Value?
 

I was wondering if someone here could help me out.

I just picked up 16 sequenced $50 Australian '06 polymer banknotes. As far as i can tell the are Uncirculated - Not a single crease in any, perfectly flat, no discolouration, and very, very, very crisp.

My Renniks value guide has them priced (Unc) at $80. Or face value for almost Unc.

What i would like some opinions on is the effect sequencing has on banknote value. Any info would be enlightening.



Cheers.
