You'll have to substitute your own currency here. I don't know what Benjamins or Washingtons are but I get the point. Low quality links don't add up to much, even if you've got lots of them

All Yankee currency has an ex president on them... I think Benjamins and Washingtons are higher values (like $100 and $50). It's a good analogy though!

Yeah, I knew they had a president on them, I just don't know which one is which.

That is a good way of looking at link building - thanks for the post.

Ben is on the $100 bill and Washington is on the $1 bill. And actually we have a few coins (at least one I know of for sure) that doesn't have a prez on them.
