Can these two larger-than-life luminaries work together to discover the source of the mayhem, or will all be lost in the pursuit of “Dangerous Currency”?''

Trivia

 * As of 2013, "Dangerous Currency" is notably the last comic book story featuring Donald Duck, Scrooge McDuck, The Phantom Blot, and any of the characters from the Disney duck comics or DuckTales and Darkwing Duck to be published in the United States.
 * Ammonia Pine, Dr. Anna Matronic, Herb and Binkie Muddlefoot, Jambalaya Jake, J. Gander Hooter, John D. Rockerduck, Ma Beagle, Moliarty, Neptunia, Pete, Steelbeak, Stegmutt, Tank Muddlefoot, and Tuskerninni are all featured on the "A" cover for Part 1, but do not actually appear at any point in the story.
 * Likewise, the "A" cover for Part 2 depicts Darkwing surrounded by Ma Beagle and the named Beagle Boys from DuckTales, but the story instead uses generic Beagle Boys like those from the original Uncle Scrooge comics.
