That seems ... odd. I can pay my apartment rent with a debit card with a fixed transaction fee (eg, $999.99 and up to $1,999.99 the service fee is $4.95), while covering it with a credit card has a different fee structure of a flat 2.95%. This is with Rent Cafe in NYC, and from what I can tell, it's a very widespread platform across the country. The 2.95% fee specific to credit cards will wipe out the points earned for a credit card under almost all circumstances.

Platforms like RentCafe are highly configurable to support local laws, because the nature of landlord/tenant law is that it is highly variable by state.

Going though that same effort is a waste of time and implementation budget for something like selling novelty bills.

Fair enough - in which case the Mint just needs to pad the sale price a bit to cover interchange fees, and make a little extra on top, and shipping can be extra. 10% on top of the face value should be more than enough, and would have the side effect of sapping any would be manufactured spend. Yet the prices on the Mint are way above that - it looks like more than 50%. Sure, if the novelty or collector market values it at that premium, great. What I struggle to understand is that this is primarily to combat manufactured spend. I still don't see why manufactured spend is a problem for the Mint to solve, rather than the credit card companies.
