Dug this very cool button a few days ago but my limited research has revealed little. Looks like a Roman style, capital letter P, surrounded by a wreath. Reverse markings say M.C. Lilley & Co., Columbus O.
I have seen these identified as Police buttons. The M.C. Lilley company started making military,state, fraternal, and police buttons and various equipments in the mid 1870's.
