[Harp-L] Greetings All .. New to the forum! .. Hoping for some help!

[termer87618@xxxxxxxxxxx]

I do metal detecting as one of my hobbies, and have been at it since 1968.  Over the years, I have excavated many reed plates from harmonicas and other instruments.  Some have come from areas of known Civil War activity, many have come from old house sites, some came out of old dumps, etc. 
I am hoping that I can find some help in possibly learning  how to identify and /or date these items so I can properly label them. Any help or thoughts anybody can give would be greatly appreciated.  Thanks, and my belated Best Wishes for the New Year!
