Who claimed to be the second richest in Duck tales?

In the original "DuckTales" animated series, the character who claims to be the second richest duck is Donald Duck's wealthy uncle, Scrooge McDuck. He is often referred to as the richest duck in the world, but in various stories, characters like Flintheart Glomgold vie for the title of second richest. Glomgold is a recurring antagonist who often seeks to outdo Scrooge in wealth and business ventures.
