Trivia

 * While reading Botaro's soul in the Old City Overlook, it mentions him having this coin on him, and that it would grant access to Dereo's hideout.
 * While speaking to Sedūzo, she mentions that Botaro showed her the marked suolenet, commonly used as a token of Príncipi allegiance. As an RDC captain, this alarmed her, and she knew that she must have been dealing with a pirate. Botaro was dragged away after Sedūzo called the guards, and it is assumed that the marked coin was discovered on his person and confiscated as evidence by the overseer.
 * Talking to Dereo the Lean, he is surprised that you found one of his suolenets. You can comment that it came from a "...man who tried to make off with your money", referencing Botaro.
