with a 'P' mint mark, it shouldn't be silver. probably just a crappy layering of the copper and nickel it takes to make the blank planchets. any more, they produce coins with high speed/high production equipment that the end result is a coin just as cheap and crappy as the chinese made merchandise it eventually buys. our nation seems to no longer take pride in our coinage as they did many years ago. the whole state quarters, national park quarters, and presidential dollar deal was/is nothing more than a money making scheme cooked up by the greedy people who run our country.... it takes about 3 cents to make a quarter, so every one that gets pulled from circulation for the sake of collecting (which was the government's intent) gives the government a net profit of 22 cents.
