Would you please explain better what you mean.
I also own several years of this coin and they certainly aren't error coins...

What you mean by error in this case though? Is the picture wrong or other info? Or something else?

he mean first line

ND 40,980,000
ND for no date?

Hmm....
Usually they do put ND for no date if it's common.for date to be worn and non-readable. For example buffalo nickels. Most of them.are with no date....
But to have mintage next to it.... Don't know. Maybe it does meqn that there was that amount minted with no date on at all...
I hope someone who knows will read this forum and answers it.

Since 2002, I haven't seen a cent coin without date. It might be an error on Numista.

Yes, it is error in Numista. The mintage of the coin is just too big to be some error on the coin.
