Harley Davidson Third Edition was my very first pin I ever owned and has too much sentimental value to it .
AC/DC is my first NIB experience and is my favorite pin to play in my collection, so it will never leave.
Stern Trek LE will never leave not because it's a fun pin to play and beautiful to look at, but because it's Star Trek LE #2. I didn't request a number and thought it was so neat to randomly get that number which I beleave is the lowest number you can get.
Now with all the hype that Iron Maiden LE is getting, it will probably never leave.
