The US code refers to them as "one-cent" but certainly does not preclude the vernacular "penny".
They're called pennies here, too:
PUBLIC LAW 109–145—DEC. 22, 2005
PRESIDENTIAL $1 COIN ACT OF 2005
SEC. 304. NUMISMATIC PENNIES WITH THE SAME METALLIC CONTENT
AS THE 1909 PENNY.
The Secretary of the Treasury shall issue 1-cent coins in 2009
with the exact metallic content as the 1-cent coin contained in
1909 in such number as the Secretary determines to be appropriate
for numismatic purposes.

It's invisible!
It's the stunningly rare error 1957 cent. I have one too but can't find it ... it's invisible.
It was the one that was launched on Sputnik.

I think this thread belongs in the World Coin Forum since "penny" is a British (or Commonwealth country) denomination.

The mint calls them pennies.
Yes, the language has evolved. Although I'm sure some of our forum curmudgeons will refuse to accept the change.

The law is on my side
The US code refers to them as "one-cent" but certainly does not preclude the vernacular "penny".
I would also point out that if you want to cling to the letter of the law, "nickel" is improper also. The code refers only to "5-cent" coins.

Penny is slang for cent, nickel is slang for 5 cent piece. Golden dollar is slang for dollar coins of a certain type.
The fact that mint or even Congress misuse the terms may or may not be significant to you, depending on how much you care about accuracy.
It is still invisible.
For the 23,513th time it is called a penny.

Try going to the bank and asking for a box of cents. The teller would be like, you need more than a box
