Have a quarter struck on nickel, can not find one the same to compare to on any forums or websites. Year is not visible, though I have found many are silver 2016s, this coin is a "p"
Best part about it, I walked by the coinstar and this was in the bottom, spit back out with a 1964 dime and a bunch if pennies the last person that used it did not take out.
That coin appears to have been spooned; this link should provide you with some insight on the practice. http://coinauctionshelp.com/spooned_coins.html#.XU8SqHt7mUk
It measures exaculy to a nickel, with smooth outside edges, all models I have saw on quarter on nickel planchets are the same look as this, with the lips aroind the inside, front and back... I could be mistaken but it looks too perfect to be spooned. Input is appreciated.
If a quarter die smashed a nickel planchet it would smoosh it down and there wouldn't be a rim. As a quarter is larger than a nickel, right? It was a quarter that was spooned or caught in a dryer or similar device and the edge was rolled in to allow the design to be flush with the "edge"
That coin exhibits the diagnostics consistent with a spooned coin, specifically the localized damage to the coin's rims. Furthermore, the US Mint in recent years has become far better at screening for error coins before leaving the mint. Thus, making such a discovery extremely unlikely. https://www.cointalk.com/threads/dryer-coin-vs-spooned-coin.304963/
If a quarter is struck on a nickel planchet the nickel planchet flattens and winds up thinner than a nickel. There is no copper color because a nickel planchet doesn't have a copper core. Your coin is not a quarter struck on a nickel planchet because the coins you have seen searching the term quarter struck on a nickel planchet aren't either because I just looked it up. In all cases those are spooned coins or dryer coins. This is not my coin. I pulled it from the heritage auctions website. This is what a quarter on a nickel planchet looks like every time. This is NOT what your coin looks like. Your coin looks more like this, more shiny, but still like this. This is a dryer coin.
It can't be a nickel because a nickel is made of 75% copper and 25% nickel which is melted together and the alloy is whitish. The quarter has a copper core which is what you are seeing on the rims, when the outer layer is taken away. It's a damaged quarter as everyone says.
