frankly this is crazy --why would a person leave a 25 cent face value American coin behind ( Washington is still on the modern day quarters ) ----much less a silver one ? unless its done for a lark to make someone's day ? ...silly or generous folks one or the other...
I have seen coins stick to the dump /lift grate before ..sometimes folks dump crappy goopy coins onto the grate and it makes it sorta tacky ..and then coins do not slide down the grate like they should
