The two machines at Verandah Breezeway and Island Supply (Lion King) have been reconfigured. They now share a cabinet in the Verandah Breezeway, and a new change machine is placed between them. The change machine also distributes 2 shiny zinc pennies with every dollar redeemed.
The first change machine I noticed distributing pennies with quarters was at the Field Museum in Chicago. This may become a trend, especially in locations where a cashier is not handy to provide change. At this point, though, this is the only change machine I have seen at Disney World that distributes pennies.
