I was roll searching and came across a 2004 $.25 Canadian that appears to have only one side plated . The reverse side is silver colour with wear and the obverse is copper colour. Any Ideas what this might be, I don't think it was a science project but am looking for ideas.

Very nice!
Plating error would be my take.

I'm actually wondering if this was a "copper plating" ... it looks like a plate job to me... I didn't even think there was that much copper in a quarter of that date..

This is a P coin so is a steel core coated with nickel, then copper, then nickel. My first guess would be the top nickel layer was chemically removed. But that's just a guess.

I think it was half plated with copper, not a plating error. About half of the quarters minted 2003 and after have much less copper plating under the nickel (white MPPS coins are a steel core layered with nickel, copper, and nickel again), than P quarters minted from 2000 to half of 2003. You can hear the difference by just dropping the quarters, the ones with more copper has a bit of a ring to it when you drop it. I experimented with un-plating quarters, the copper layer on the 2012 doesn't survive one electrolysis (the one using nickel acetate, and that is only supposed to remove the outer nickel layer), but I never got to the core of the 2001.

I believe it is a PMD, it not only looks like it has been cleaned almost with a toothbrush, but it has the look of a chemical. This is not what a genuine error would look like.

Never ceases to amaze me. Yes this could be the result of someone having added some copper plating after the coin left the Mint, as much as it could be the result of a process going wrong at the Mint, where too much copper plating was added. And yes this could be the result of someone tampering with the coin after it has left the Mint, as much as it could be the result of a process going wrong at the Mint, where the additional plating could not adhere due to impurities. Maybe the plating was destined to fall away from the coin, due to a process going wrong at the Mint. Does this count as a Mint error or is it now considered as PMD. Not like we don't see and show coins on a regular basis that are less than perfect, that do come from the Mint. With the number of coins being stamped out every minute, what makes so many believe that every single coin gets a special 5 to 10 second scrutiny. Imagine the staff the Mint would need to achieve such a feat. I like the coin, it really doesn't matter to me how it came to be and I would be happy to have a coin like this in my collection.

Years ago part of my job in maintaining a large mainframe computer installation was a requirement at times to gold plate contacts on the boards in side of the computers. Once I was done plating what was required for work there would always be some gold left on the swab. Befor disposing of the swab I would gold plate any quarters in my pocket for pratice / for fun / and it looked amazing. I didn't keep any of this change, at times now I wish I did but at the time it was fun to include a gold plated quarter as part of my tip when I went out for dinner. This was years before the loonie came out so I would always wonder what people would think when they found this "gold" coin in with their tips. Cheers Liverpool

A note about my last entry: At the time that I plated the coins I didn't even know people collected coins, If ended up confusing collectors it was not my intention, even now as a collector I would not mind having a couple of them back in hand.
I made this post in the hopes of adding to the discussion on where do "odd" things come from. respects, Liverpool
