Missouri Harmonica Reed Plate Value Guide
Harmonica Reed Plate is a realistic Missouri detector target tied to old homesteads, low-water crossings, and CCC park sites.

Missouri state guide
Metal detecting in Missouri is usually governed by who manages the ground rather than by one blanket statute. Municipal beaches and local parks may allow it, while archaeological sites, battlefields, historic structures, and many state park units are restricted or off limits. That matters in old resorts, CCC parks, and farmsteads.
