If you compare the size of the devices with other years they are large on that years coins. But they all looked like that that year. There was a swollen master hub that year. They replaced it with a new, new master hub the following year:

Note the locations of the devices changed and the bust is even smaller. If they had changed it during the year, there would have been a large and small date that year. (Like what happened on the Cents) but they waited until the following year to change over the Master hub.
