The three leftmost items were discovered in my back yard today. An hour or so of searching revealed these, as well as the badly rusted and corroded remains of tin cans and some aluminum foil from some disco-era cookout. Or Reagan-era.

The three items were some kind of a metal bracket or brace, a pink car, and a cent.

The other stuff was found at a local elementary playground. I poked around for an hour until it got dark. Half of the coins were found in the first ten minutes, in one little spot.
