OK< this is what I do for parking meter change - I bought one of those $2 zippered little pouches from the men's wallet section of Wallmart - it is black, zips shut, is about 3.5" x 3" and easily holds about $25 worth of change. Keeps it from rattling around and easily available. I keep it in the center console in the little tray, but it could be kept anywhere. Works great for me.
