Civil War Relic Hunting

Can anyone recommend some reference books for Civil War relic hunting? MY SO would enjoy this, but am needing some help overcoming the couch inertia! Thanks

Most Civil War battlegrounds being maintained by the government forbid metal detectors. If your guy has thorough book knowledge of the era, perhaps he can locate a likely spot on private property. Then convince the owner to let him hunt…

Otherwise, how about shopping? There’s a guy on Antiques Roadshow who is in the business & I’m sure there are many more. Lots of fakes out there, though.
