There are no examples given in "the literature" that you read?

Spin one-half. Or a system of coupled spin one-halfs.

I'm not sure what is meant by "no classical limit." A white dwarf star in a sense is not a classical limit, even though it is a huge number of particles, but if you heat it up high enough it would explode and be a very classical type Ia supernova.
