Let \(A\) be the coordinate algebra \(\mathcal O(V)\) of some quantum space or group with parameter of quantization \(q\). A semiclassical limit of \(A\) is an algebra over the Laurent polynomial algebra \(k[t^\pm]\) where \(q\) in the defining relations of \(A\) is replaced by \(t\). The paper considers connections between the prime spectrum of \(A\) and symplectic leaves of the semiclassical limit, between primitive ideals in \(A=\mathcal O(V)\) and the symplectic core in \(V\). Some conjectures are formulated.
