I plan to never sell my Parker 51, nor purchase another for that matter, but I've been wondering how much it's worth. Are blue diamond Parker 51s worth more than later ones without the blue diamond. Correct me if I'm wrong, but most P51 Vacumatics have the blue diamond.

The cap is gold filled, with a tiny, almost unperceivable dent, and the pen is completely restored. All the parts were cleaned in an ultrasonic cleaner, and the diaphragm is new. All other parts are original.

It's from the 4th Quarter of 1945.


Thanks guys!!

Worth more than what, specifically? Worth how much more than what?To whom? Lots of questions arise.


It can be helpful to know some generalizations, but my own experience of shopping for pens and seeing them go for quite a bit more or quite a bit less than might be expected has given me a guarded attitude toward such ideas as "other things being equal."

I am not a collector, so I cannot really answer your question. I can add that some of thr line styles on thr gold filled caps seem to be less common and thus are offered at higher prices.

I prefer the caps with the blue diamond but it also introduces another potential condition issue if paint is missing or had to be refilled. So a blue diamond cap with thr blie.mostly gone may not loo as nice to a buyer as one with just the arrow.

If you want less blah, blah, blah and more pictures, follow me on Instagram!

Unless there is a specific feature such as cap design or color that commands more, all Vac filled 51s are worth about the same no matter which clip they have.
