A very clever and inventive adventure! Taking something as simple as a coin and then basing a whole story around its travels. The ending was a nice wrap up to that whole chain of events. The sound effects were very good and clear, bringing to life all the different characters, scenes and backgrounds.
The animation's quality fluctuates from sometimes good to sometimes bad. To anyone who is enthralled into the story, they won't notice the details, but things like the line scribbles representing a pile of coins can sometimes ruin the experience for others (although, funny enough, if the picture came through to your audience correctly, there's not much to fix). It didn't affect me too much but it's something to consider in the future when you make another cartoon. Good job! 4/5.
