Well done. First nickel is cool and welcome to the club.
On my E-Trac a nickel shows up as 11-11, 11-12, or 12-12 on my screen. However, so does a beaver tail tab. So, I dig it anyway. Over the years I have found enough pull tabs to build a forty-foot boat with a quarter inch thick hull. 
Is that the nickel in the last pic? If so, it looks like a V nickel, and that is cool!
