The towers on the walls might on the actual wall be of equal size and equally spaced. A photograph of them would show the ones on the far side much smaller and closer together, which is a feature of perspective. The coin shows the towers of the same size and spacing. The coin does not use perspective. I am still looking for coins where "things further away look smaller." The Zeugma coins would be a good example if they depict a temple courtyard. However, it may be that our modern eyes are so used to perspective that we see it as a courtyard because we expect perspective. The argenteus above proves that sort of perspective was not always used, even decades later. The galley of the OP shows oars further away as smaller. It uses perspective. Please post another example if you know one.
What do you make of this one? It's a frontal view of a city gate, but it would check the "further away as smaller" box. SEPTIMIUS SEVERUS AE29. 12.6g, 28.8mm.

A perspective on Roman sewers - with the added illusion of perspective in the "small person" on the right facing right, which is really not a person at all, but a column on the right side of the platform.

Wow - @PeteB ... that is not a coin I have ever seen before. It is quite amazing in all respects. Can you please tell me more about it? Spectacular!! ---- Nevermind... I found it on your website: http://akropoliscoins.com/page4.html What a wonderful thing.. although it is just a hair over my budget!
Here's a Caracalla from Alexandria Troas with the Temple of Apollo Smintheus from an angled perspective.
I suppose in the obvious cases like this Ariel view of city walls if you look at the back entrance is slightly smaller in width than the front entrance, showing a form of perspective. And you know zumbly you always have a buyer for that coin if you get sick of it.
@zumbly, @Victor_Clark posted a great thread about this type, "Diocletian Campgates." I'm clueless about the relative scarcity of a Maximian one, but your example compares favorably to his.
