Hi @bagdbmba,
Thanks for the appreciation.
As explained above, "for" is required so that the comparison has no ambiguity. Given the context of the sentence, I think it's ideal to place "as a substitute" before "more". However, I wouldn't say the second version is correct since it doesn't have "for" before "the dollar bill" and hence contains ambiguity.
Hope this helps!
