At the risk of coining a new phrase, "It's about the money."

Dollar bills are the creation of, and owned by, the Federal Reserve System.
Coins are produced by the Bureau of the Mint.

HUGE difference.

Coins are government specie - when the government mints coins, they are
minting money. When the Fed prints a dollar bill, they are producing a
promise to pay. Not the same thing at all.

All the coins produced by the mint are new, free, money that the government
can spend without borrowing. Not so with paper.
