Depends on the condition. Is it a double struck coin? The date on some of these cents was minted in error and it "appears twice" on the coin. That penny is worth some money. Anything else is worth less than a buck. Usually a lot less. Even the uncirculated1955 D cent is selling for less than a buck.
One Cent is the value. The US has never made a silver penny. It may look like silver or have been silver plated but it has no collectible value.
50 cent
3-10 cents, depending on condition. It's not a rare coin.
Uncirculated $1 to $475 depending upon the condition of the coin.
That wasn't something done at the mint, rather the cent was likely plated with zinc or nickel. So it has little to no collector value. The US government has never struck a penny in silver.
A lot
Retail for circulated coins is 5 to 15 cents. Excellent uncirculated examples are under a dollar
3 cents.

At the most 25 cents
The coin does not exist, the only possible mintmark for a 1964 Lincoln cent is a "D'. The "D" may have been damaged during or after the minting process but the coin is only worth face value.

It's worth 2 cents for the copper.
Around 3 cents.
