Italian Applejack $10-15
Italian Windy in walking pose $13-$17
Italian Skydancer $15-18 if in VGC
Italian tropical Parasol $10-$12
Italian regular parasol ~$10
German Moonstone with chewed horn $10-15? Am not good at pricing unicorns with chewed horns, as this flaw is close to an absolute No Go for me personally.
This is what I would price them at, would be interested too what others say.
I'm no help with pricing greeks and peruvians, I got my decarded Greek white Skydancer for $170 once but she had her original tail and I think she was probably quite expensive.
