I have a 1965 quarter that has a few different defects on both sides and even the rim. I have a dad and a son who used to work at the Sunshine mint before they closed it down, but there they only dealt with silver coins so they could only give me a limited opinion of what could have happened during the mint process. From everything I've read up on and heard I came up with a very vague theory. This is my guess- That maybe during the process of making the clads it something got missed during the firing/hardening stage there for causing weakness for when the die press came down on it. Notice the reeded edge and rim. Then there is the disconfiguration of the two sides and the blobs (I forget what they call it) notice behind Washington's head it almost resembles a large 2. I know some of my wording/English may be somewhat off, but I'm hoping you get what I'm trying to say. I understand if you laugh, I laugh, but please don't make fun of me or be snotty. Thank you for your help. Holding25   |

See how the copper layer is lower than the clad? That means that it was dipped in acid that was strong enough to completely dissolve copper, but not the clad bit.  to CCF! |

 Anything acidic can cause that - like sitting in a pool of cola in a car cup holder. The reeded edge shows that the die collar was in place when the coin was minted. I can't quite make out the blobs behind the portrait -- I just see discoloration. It's not always easy to get photos of blobs....anyway, my guess is that the blobs are also some form of damage -- most likely the same thing that corroded the edge. |

@H25, first welcome to CCF. Second, I agree that your quarter looks like those that have been soaked in acid to preferentially remove the copper. Save it if you want, but there is no numismatic value beyond face value.

Okay I did some experiments and did an acid test. It did nothing but oxidation on the nickel part of the quarter and turned the color of the copper a light pink color which buffed right out to shiny again. So I must not be using strong enough acid. I soked it all day. And when I did the pop test I let it soke for 4 days. Has anyone else done this? Just wondering. I'm not going to be able to let it go until I see it proven how it was done. I can't help it. So please more help. Thank you for your replies

Thanks for sharing the results of your experiment. Maybe the damaged quarter spent years in acidic soil or at the bottom of some wishing well. I don't know if the strength of the acid is the only factor. It might be one of those things where a long exposure is what matters.  |

Pure copper is much more chemically reactive than the cupronickel alloy so a corrosive environment will affect the core more so than the outer clad layers.

Are you trying to get me to the ocean? Lol just kidding. I seen something like it. It was a coin from Hong Kong I think and it was perpously made that way. Which is one of the reasons I thought maybe an error. Another is because I've seen some parcial collar errors where just part of the quarter edge looked the same and of course because it is a 1965 the first year of the change. So I thought maybe could have been one of the first made with mixed metals. But I think I'm giving up on that. Thanks again for all your replies and help.  |
