Maybe there is a detective as one of the main characters in the 'gold watch story'. If the gold watch was stolen, the detective would be trying to solve the case and find the watch. There could also be the owner of the watch, who is desperate to get it back.
It could be a soldier and his commander. The soldier might receive a gold watch from his commander as a sign of honor for his bravery in battle. So the two of them would be important characters in the story as the act of giving the gold watch is a significant moment in their relationship and in the story as a whole.
Since I don't know the exact 'gold watch story', it's hard to say. But it could be a grandfather who owns the gold watch and his grandson who inherits it.
Since I haven't read it, I can't say for sure. But it could be the owner of the gold watch, maybe a person who covets the watch, and perhaps a character who has some sort of connection to the watch's origin.
As I don't know the specific 'gold a true story', I can't say who the main characters are.
The main characters are Maria Altmann and Randol Schoenberg. Maria Altmann was the woman who fought to reclaim the 'Woman in Gold' painting as it was of her aunt. Randol Schoenberg was the lawyer who helped her in this legal battle.
The main character is probably the king, as the name 'king gold story' implies. There could also be a character who tries to steal the king's gold. Maybe there is a magician or a thief who plays an important role in the story. Another possible main character could be a poor person whose life gets affected by the king's gold, either in a positive or negative way.
In some 'city of gold stories', there could be local guides or natives who play important roles. They might know some secrets about the location of the city. The main characters also could include greedy conquistadors who were more interested in looting the gold than understanding the culture of the place. And sometimes, there are wise elders in the story who try to protect the city of gold from being discovered by the wrong people.
Since I haven't read the specific gold coin story, I can only guess. There could be a protagonist, perhaps a young adventurer who discovers the gold coin during his journey. There might be an antagonist, like a cunning old miser who wants to take the gold coin away from the adventurer. And there could be other supporting characters such as the innkeeper where the adventurer stays and who gives him some advice about the gold coin, or a wise old man in the village who knows the true value and the history of the gold coin.
The main character is likely the 'Gold Star Kid' themselves. There could also be supporting characters like friends who either help or compete with the kid. Maybe there's a mentor figure in the story, someone who guides the kid and helps them earn that 'gold star' through advice and support.
I don't know the specific 'Gold Coast short story' you're referring to, so I can't say for sure who the main characters are.
Maria Altmann is the central figure in the 'Woman in Gold' true story. She was a determined woman who refused to let the Nazis' actions go unchallenged when it came to her family's property, especially the Klimt painting. Randol Schoenberg, a lawyer, was also a key character. He used his legal knowledge and skills to support Maria in her fight against the Austrian government and institutions that held the painting. Their partnership was crucial in the long and arduous process of reclaiming the painting.
Since I don't know the exact story, I can't say for sure. But it could be a young adventurer who finds the gold coin, an old collector who is interested in it, and perhaps a villain who tries to steal it from the finder.
