I find buttons to be interesting finds. I collect all I find.
I've been detecting since Jan. 2001. My oldest find is a lockplate to a flintlock rifle. My oldest coin is a 1837 Capped bust dime. My best find is a T. Miller Cavalry Button. I use the Minelab X-TERRA 705 and BH Tracker IV as a backup.
Buttons are always a welcome find. There's a really good post from Buckleboy on cleaning buttons. Don't know if you have seen it or not. http://forum.treasurenet.com/index.p...,165857.0.html I don't use any water at all on buttons. Not even for an initial cleaning. The water washes away any contrast on the backmark. I'll rub them with the flat side of a toothpick and then rub with my fingers. The oil on your fingers will really make the contrast stand out. If you're finding a lot on the same site that is a good sign. Hunt that place to death.
