Answer1921 is not a rare date for Lincoln cents.

Well-worn it's worth about 10 cents.

Lightly worn it's worth about $2.00

A nice uncirculated one is worth about $30.00

If the coin has a small "S" under the date, it's worth a bit more - $1.75 / $5.00 / $65.00
it can be worth 20 cents to 75 dollars depending on grade and mint mark.
