A manga with a scene of a group entering a city and learning that they have to pay 10 silver to leave
Arata Kangatari is the series you are looking for.
It took some thinking, since I dropped it a few years ago, but what you remember is from chapter 53 of the series.
Here is the last page of the chapter:

Synopsis of Arata Kangatari from mangaupdates:


Every 30 years, a new princess is chosen from the Hime family to serve the Hayagami. The time has come again, but over these past years, records state not a single female has been born, save for one, the 15-year-old Arata. The only problem is, Arata is actually a male! Forced to disguise himself and take the place of the princess candidate until a formal one can be found, he attends the festival only to witness the current princess, Kokuri-hime, murdered, and his own life is forfeit as well, by the hands of the princess' personal guard, the 12 Shinshou. As he runs for his life, Kannagi of the 12 convinces everyone that Arata is the one who has murdered the princess instead, and now everyone in the Imperial Court is after his head! Now, another Arata from our world has crossed over in Arata's place! How did this happen, and how will these two survive?
