These are cels are most likely ones that Micke is 
still quite attached to and definitely isn't in a 
hurry to get rid of them.

Quite a few private collectors and dealers often 
do this... setting prices on their personal high 
end cels such that only the most die-hard 
collectors would be willing to purchase them.  
Either the prices are set at a level that would 
justify to the seller (in their mind) letting 
them go or that would weed out those who may not 
be serious enough about those cels.  (No offense 
to serious collectors who just can't afford or 
are not willing to pay such prices, but that's 
just the way things are at times.)

In such instances, market prices have nothing to 
do with the pricing but more to do with how 
willing the seller is ready to let go of these 
cels.

When you see a collector's page which states that 
their cels are NFS (not for sale) but they may 
consider selling them at irresistible offers that 
they cannot refuse... this is sort of the same 
thing (but now you see actual numbers).  So 
there's not anything wrong or unusual about this.

Micke sells cels regularly on the market (and 
often bargain) level through her auctions, so 
don't believe that this particular occassion is 
her usual standard of practice.
