Damn I love Don Rosa comics.

Is this from the one where they found Croesus' vault to make the amulet from his lucky coin?

Life and Times of Scrooge McDuck is also not only a happy story about him getting rich, but also about becoming lonely and somewhat bitter in the later stories.

Highly recommend reading them, Disney likes sweep them under the rug for whatever reason.

The treasure hunt series (where I think this picture is from) is a bit more light-hearted in nature, but still very good.
