There are two machines in the zoo:
One by the concessions and the other is by the exit of the reptile house.
Each have four designs and all are 51¢.
The designs (all have a dotted boarder with "pennycollector.com" and the text "John Ball Zoo"):
An ape walking on all fours, a bald eagle, a snake on a branch, a penguin, an otter, a snow leaopard, a tiger, and a lion.
