Welcome to the Forum It sounds like split plating but will need clear photos of both sides to confirm.

Glad to see that you are learning Sharran. It is better than just posting every piece of pocket change like some people and hoping that someone hear can find an error on it. You can’t always tell the difference between zinc and copper but most of the time if you look at the fields (the surface), you will see that on zinc coins it has a more textured appearance and maybe even shows signs of plate bubbling. If you look at a copper coin, unless it has been damaged, you will find that the fields are smoother. The last coin posted is a good example of a zinc coin.

Agree, badly damaged. You cannot have a coin that is struck in collar out of round as that one is. PMD

Correct, that is a Small Date.

That 43 has been plated. It would show a steel rim sandwiched between two layers of zinc if it wasn’t.

A coin

Right, except the OP's coin is a 1983.The same theory still applies though.

What do I think? I think it has been plated. Show a photo of the edge to verify.

Canadian 25 Cent pieces. Year can be anywhere between 1912 and 1936. Only worth silver value in that condition.

Where did you get the idea that there is a 1983 Small Date, they are all the same.

Welcome to the Forum Is it incuse or flush with field. Can’t be a shadow as it is pointing the wrong way.

Don't know what this has to do with Registry sets but anyhow, please show a clear closeup of the date and mint mark.

It is just damage. You cannot have only part of a coin double struck, the whole coin would be double struck resulting in everything being doubled.

It’s a die chip, no extra value.

Looks like an ordinary CENT to me. Grading cost $50.00 Value 1 cent . It’s your call.

A well placed linear plating bubble. Can’t quite tell what’s going at the top of Abe’s head

Not an error, it’s damage. Vending machines will also cause this damage. Crimping machines are usually closer to the rim.

Not an error, it's damage. Looks like it has corroded.

It is a slight MAD (Misaligned Die) . No extra value.

It's an impaired Proof, it has been damaged.

It is worth one dollar, why spend $50.00 on getting it graded

The silver coins would have a S mm and weigh 6.3g Take it out of the 2x2 and weigh it.

Hello again- That is PMD (post minting damage) When you see a coin that has been struck in collar and is out of round, then you know it is damage.

Not an error. that is called a ridge ring caused by die deterioration. Just a die event.

Just some sort of environmental damage. It certainly didn’t happen at the mint whatever caused it. Look up the meaning of Cud when referring to Numisamtics
