rascal said; " two of them is the 2006 doubled die and the 2011 doubled die. these are doubled on the outer edge of the coins like the 55 and 72 doubled dies but not as strong but still nice." The 2004 Lincoln cents yielded two strong DDRs, and 2006 yielded many DDOs including the doubled ear lobe (DDO-004) and the very popular DDO-003. With the new Lincoln cent series, the 2009 Birth and Childhood design, minor doubled dies have been reported for the obverse and reverse. Many collectors are not aware of the fact that most modern doubled dies are more likely to be found in the center of the design.
I see this in a lot of newer shiny coins, but then when I tilt the coin it disappears, because it was sort of a "reflection" from the lighting. Try tilting it to another angle and see if you still see the "doubling". Even if you do, it's still not a doubled die.
Looks like triple strike doubling to me. Very cool and definitely a keeper, even though its not worth a whole lot.
