Harley-Davidson has a few different styles of authentic 105th anniversary pins

The first 105th pin released was part of the 105th anniversary "Riders Pack" (which included pin, hat and bandana).  This pin has a black background and a fairly flat face.  The metal has a shiny chrome-like finish.  The back has a 2007 production date on it.  It is 1 inch wide by 1 1/8 inches tall.

The second 105th pin released was sold by itself.  This pin is the same size, but has no background color.  It is all metal.  The metal has a much more matt finish than the previous pin.  Also, the face is much more raised than the previous style pin.  It has a 2008 production date on the back of it.

The confusing part is that the Harley website showed a picture of the the first pin when referring to the second.
Hopefully, this clears up any confusion.

I have both types of 105th pins available in my eBay store.

They also offered a larger sterling silver version. I'll be adding more pictures as soon as I can.

They also offered a similar pin at the 105th anniversary event in Milwaukee.
