A fun thought experiment: how could you go from selling $10 bills for $5 to selling $10 bills for $15?
Edit1:
/s
Slightly more seriously, you could promise to anyone who bought a $10 bill that in some x number of years they could redeem that bill for $20. This is called "being the Treasury and Federal Reserve".
The hard part is finding a way to invest the $5 of profit they gave you in an asset which will appreciate faster than your promised return.
Edit2:
This is not advisable, see "Bernard Madoff, Ponzi Scheme".
Electronic/Smart bills, that keep track of how many times they've been used to purchase stuff with.
After a bill has been circulated N times, it increases in value by Y, and/or unlocks special artwork.
Some bills may become highly sought-after collectibles worth far more than their face value.
Would it help or harm the economy?
Nations try to avoid this because they can spend freely on a promissory note currency system. It is a recipe for disaster in the long term.

- Step 1: Switch to selling $11 (2 x $5 bills + $1 coin) for exactly one $10 bill, cutting your net loss per trx by 80% and showing how serious you are about going profitable. But its just a ruse, what your really doing is capturing the market supply of 10$ bills.
- Step 2: Once you have this, you can now start selling branded $1000 laptops for $10 (bills). Increasing the value of $10 bills and allowing you to offload your existing stock of $10 bills for $15 (or more).
At this stage you now have (a) an incredibly profitable 10$ bill business, (b) a spectacular growth story in the consumer electronics space with (c) proven ability to reach profitability.
