Has Debasement of the Nickel Begun?

For over a year now I have been warning that the government, after debasing dollars, dimes, and pennies, would turn its attention to debasing the nickel.   Here is one such article.  Here is where I called for any new debased nickel to be substantially different in appearance from the old nickels so that people can tell them from the phonies.

Today, I found a 2011 Nickel that superficially looks the same as some of those from the previous year, but feels different.   I believe that the Obama administration has already debased the nickel, which until this point was 75% copper and 25% real nickel.  The new one feels like it is made of aluminium or something.  I have looked, and can find no news stories about this.  Compare a new nickel to the old and tell me what you think.
