Hm... I'm afraid I never read that story (someone said two years ago that 
there's a lot of Barks I haven't read, and unfortunately it's still true), 
but... Am I the only person being reminded of Geoffrey Blum's "From Dime to 
Dime" ("Dime and Dime Again") when hearing this?

Are the two stories relatively similar around this?

If so, does anyone know whether this was an intended hommage or plot theft, 
or if this is a coincidence?

I get a feeling that this part of the story is similar in both these 
stories, and Geoffrey Blum of all people must have known about this Barks 
story (even though I didn't). So, if they are as similar as you give me the 
expression of, I'm curious to whether this was an hommage, a theft of plot 
Blum hoped nobody would notice, or a plain coincidence. Does anyone know?
