I just sold a decent Hopscotch for $15. I would agree with $10-$20 based on her condition, yours looks good.
Can't be 100% on the others, though I would think the haircut on Baby Hopsi would cut her value. She seems more common than Baby Bloemen and Baby Kirschblute but it would need someone from that part of the world to comment to know for sure.
Crumpet is always quite sought after. To me $30-40 for Baby Crumpet seems a bit high without her purse, but I might just be out of date with pricing on her.
