It's possible it is a weak strike as Lincolns are known to have weak strikes in that area. It is also possible that it is a partial grease filled die. Cannot say for sure as your photos are out of focus. In the future, crop your photos and show both sides of the coin. In order to help you , we have to be able to see all the small detail.

Welcome to the Forum Agree with everything Just Bob says. These turn up almost daily on this and other Coin Forums, mostly high school experiments.

The variation on a zinc Lincoln is .12 so the maximum should be 2.62. Yours is .12g overweight. Possibly produced from a thick planchet. Also the target weight of a copper cent is 3.11, not 3.00

Hard to tell from the photo but is that marking on the steps raised or incuse?

Welcome to the Forum. I have asked that this post be moved to an appropriate forum, this is the Forum for buying/selling coins. As far as your 1959 CENTS go, one appears to be uncirculated (this is the way they look when they are first minted) while the other has been circulated. Copper will tone once it has been been out in the wild so to speak. Certainly nothing special

Not an error, just damage.

Nice find. That is called a delamination. Make sure you keep the two pieces with the coin. A word of advice, flatten those staples before they scratch another coin.

Bubbles caused by Zinc dust. In the future, please show a complete photo of both sides of the coin.

Seeing that those sets sell for between $8-10.00 (with the exception of the Type 2 mm), it would cost you way more than that to have one coin graded Leave it as it is

Unless you think you have a $150.00 coin there, then NO, it’s not worth grading.

Welcome to the forum Not a Doubled Die. Looks Die Deterioration Doubling Keep looking

Just one of many miniature coins in different denominations on the market today.

The only ones I know of were gold plated bronze with a weight of 24.8g which would make more sense if the gold was removed. These were manufactured as an advertising token for Sudbury. If there were gold plated silver ones made, they would be ones I have never seen or heard about. Possibly as you say they are for the US market.

As far a I know, they were all gold plated. Wondering if the gold plating has been removed. The strike looks rather weak compared to the gold one

Just a badly damaged coin. Sometimes you may never know exactly what happened to a damaged coin but if all you need to know is that it could not have happened during the striking of the coin so it is PMD

I don’t see any eagle head on Washington but I do see a badly deteriorated die on both sides.

Welcome to the Forum Hard to tell anything from those pictures because of the glare but it looks like it may be Machine Doubling (the worthless kind) Also I don't really see a die crack, can you point it out?

Looks like the Obverse may have been plated at one time and it is starting to wear off. Whatever caused it, its damage as that didn't happen when the coin was struck.

They should weigh 3.11g with a tolerance of .12 so yours is at the top of the acceptable scale.

I agree A struck through would be incuse. Those marks appear raised.

Welcome to the Forum There are many members here who will be able to help you. Post a clear picture (we have to be able to see all the detail) of both sides of the coin and point out what you think is an error. Someone will then be able to answer your question.

Hi again- Agree with the glue and acetone that Coinbuf stated. Also what you are referring to as “ghost letters” are just circulation markings on the coin that may appear to be something else. It’s commonly called pareidolia, seeing something that isn’t there. Remember that an error can only happen during the actual striking of the coin. The devices are permanently engraved into the die so ghost lettering just can’t happen. There are a limited number of things that can cause an error but there are countless things that can happen to a coin after it has been struck that can cause damage.

Looks counterfeit to me. Date is off, lettering on reverse is off.

Please explain, what do you see as a"rare" error. Looks like a regular CENT to me.
