About a 2 months ago, on a whim, I picked up a NOS 21 Super, in the original box (but missing the mechanical pencil, it appears) on ebay. I haven't had a chance to look at it until just today (it's been a rough 2 months!). The pen really does appear to be unused. Definitely never inked. It's possible that the cap was taken off and put back on, but there are no finger prints on it, and there were no finger prints on the squeeze filler, either. I paid a whopping $27.74, including shipping, for this pen.
Now here's my dilemma: The pen was purchased so I could use it. I wanted an older pen to take with me to work and use with permanent inks (Noodler's Black or Polar Blue). But now that I have it, I'm wondering if it's worth more as a collectible unused than as a daily using pen.
What's the opinion from Parker collectors? Keep it "like new", or use it?
