This was found in a planter, Outside a grocery store. (Denver Co) I would guess that it is a stolen jug. Maybe someone didn't want it anymore? If anyone has any information please Pm me. The Granby chng token is a 1990 D Kennedy half, and the copper is a cinco centavo. I was pretty excited to find more than the Jar.
Did the store have a coin exchange machine in it ? If so, maybe someone cashed in the coins but did not want to take the jug home. The two coins inside could have been rejected by the machine.
At my Coinstar #1 (CVS), the people who dump coins are notorious for leaving their dump jars/cans/etc...
