T...my highest respect for your professional attitude in this sour mistake, taking your loss as a man. Hats off for you.
Jaykeen posted a good sample to count the teeth, stick it on a piece of glass and do the counting with a fineliner. See also the replies from Rolli and Kye-lin.
What I would suggest: why not ask on the forums the interest for the right crowns, then you will know the amount needed and calculate your price including the wholesaleprice for the wrong crowns.
This way all buyers will contribute a bit to soften your loss.
I will definetely take a few.
There are a few members here on RWG owning gen Pams, maybe they could chime in?
Uncle Jay, Golfman?
Hope it works out....
