What is a 1989 D zinc penny worth?

Answer 1

Without a better description it's hard to say. There are 3 possibilities I can think of:

It's a double-delamination error, meaning the copper-nickel cladding came off both sides. Such a coin would be thinner and lighter than a normal clad dime. That's a moderately unusual error and would have to be verified in person by a coin expert.

It's a different thickness or weight but is not a delamination error. This would be a so-called "off-metal" strike that occurred when a blank for a foreign coin accidentally got into the press hopper. Again, this error can only be verified by inspection.

It's the same thickness and weight as a normal dime. Someone who has just learned about half-reactions in high school chemistry took some copper sulfate and plated the dime. (Yeah, I did this too!) As such it's an altered coin and is only worth face value.

Answer 2

If the coin has the standard copper coating, it's an ordinary circulation coin like all the other cents in your pocket change.

If it's silver in color, it could either be plated (again only worth 1 cent), altered with acid (again only a penny), OR a mint error that occurred when the coin was accidentally not put through the plating process to add its copper outside. That's a scarce error possibly worth up to $100, but you'd need to have the coin examined in person by a specialist in errors.

Answer 3

A 1989 D zinc penny is worth face value, which is 1 cent. These coins are not typically valuable to collectors unless they are in mint condition or have errors.

Answer 4

1 penny
