@numa, sorry but your quarter is neither rare nor a mint error (nor an oreo...) Rather it has been damaged by exposure to a corrosive liquid, such as an acid.

 to the CCF! Yep, it's damaged. When a coin is placed in acid the copper and nickel dissolves at different rates. That's why the softer copper core is smaller than the harder cupronickel clad layer. It also accounts for the pitted, dark surfaces of the coin. If you weigh the coin, it will most likely come out underweight due to the amount of metal that's been eaten away by the process.

to the CCF  acid damaged coin. I'm not sure it can be spent as a vending machine will likely reject it due to being way underweight. Take a look at my other hobby ... http://www.jk-dk.art |

I used to have ne of these too (gave it away) just an acid dipped quarter - the copper is softer than the cupronickel cladding and will dissolve faster, creating the ridges. |

Agreed, acid damage. PMD. Not an error. Errers and Varietys.

I used to make these for my chemistry classes to show the kids what nitric acid does to a coin.  When people see a crack in a car's windshield, they don't automatically think the car came off of the assembly line that way. Coins need to be approached in the same common sense way. Until ebay shyster auctions and clickbait online videos were as ridiculously common as they are, most people didn't let excitement over possibly hitting a jackpot (not saying you specifically are) interfere with seeing coins the same was as they would the windshield mentioned above. Now it seems everyone is more sensitive to automatically thinking "Rare error coin!" instead of "damaged coin." So we get a LOT of people asking this kind of thing daily. The reality is almost every odd looking coin is going to be PMD or something inconsequential to the coin hobby. How much squash could a Sasquatch squash if a Sasquatch would squash squash?

What's an "oreo"? Another made-up ebay term? |

In this case it refers to the edge of the coin looking like the edge of an Oreo cookie. John1  |
