Dragonhide
Armorsmiths can work with dragonhides to produce masterwork armor or shields for the normal cost. One dragon produces enough hide for a single suit of masterwork hide armor for a creature up to one size smaller than the dragon. By selecting only choice scales and bits of hide, an armorsmith can produce one suit of masterwork banded mail for a creature up to two sizes smaller, one suit of masterwork half-plate for a creature three sizes smaller, or one masterwork breastplate or suit of full plate for a creature four sizes smaller. In each case, there is enough hide to produce a small or large masterwork shield in addition to the armor, provided that the dragon is of at least Large size.

23000*0.75 = 17250 (bones)
