What colors are the most valuable iin the Parker 51?

[rizo]

The Parker 51 have many colors, but not all are equally valuable. What they are the most valuable and least valuable? Is that the more valuable the Plum but what about the others? For example, what it is more valuable the Nassau Green or Green Forest?


I would like a scale of all colors to leave the issue settled.

It's complicated. Nassau green single jewel is less common than nassau green double jewel, for example. Single jewel was export. Complications arise from number made, number sold, number discarded, number preserved. I think the vacumatic 51s were generally made in smaller numbers than the aerometric 51s. Some colors are very common surviving, others less so, and there doesn't seem to be a catalog of them. You have to read the info available and find out from experience which ones are commonly found. It isn't like coin collecting, where numbers minted are known and who destroys money unless the government melts the coins down?
