Hi Snoudel,
I take it you did not buy this pin?  This person, and a few others, have been selling tons of LE 100 super hard to get DA pins.  I have seen originals and counterfeits side by side, and the difference is minimal, but yet, I can tell the difference, only when I happen to own one of the ones that they have sold.  I have so many friends that have been taken by these sellers, so I hope you are not going to end up joining them.  
 
Good luck with getting the pins you are looking for, and please be careful.
