Love & Money

If money could procreate what would it give birth to?
Assume I lit some candles in my room, scattered paper hearts over the bed and floor, and put on some Barry White to help set the mood. I then left two 20’s on the bed, and took my kids and wife out for the evening to give the 20’s some privacy. Now I’m just wondering; if the two $20 bills did conceive, what would they get pregnant with? Would they give birth to 1’s that would mature into 20’s, or would they just give birth to smaller, miniature 20’s that would grow to normal size 20’s over time? Maybe these are not the only two possible scenarios. Maybe they could get pregnant with any denomination of bill: 5’s, 10’s, 50’s, or even 100’s? Or is this all a moot point since 20’s are marked with the face of Andrew Jackson therefore making them male by default and unable to procreate?
Just wondering.
