200 Korun Construction of Bohemia B-5

This piece belongs to the Czech National Bank's long-running commemorative silver program, which has issued themed 200 Kč pieces almost continuously since 1993. The "Construction of Bohemia B-5" designation refers to a specific architectural or engineering subject within that series, though the B-5 classification is a catalog grouping rather than anything stamped on the coin itself. Czech commemoratives of this type are struck in both proof and brilliant uncirculated finishes, with mintages typically kept below 20,000 — modest by Western European standards but sufficient to keep secondary market premiums restrained.
