I have something I would like to say about these "test" notes.
The more bricks and bricks I go through, the more I am convinced that there is something different.
Yes, there is a thinner paper- but it is a paper.
But, there is a different feel, and sound, and the way the notes behave together I can only describe as this:
They seem to bond together. Leave them flat and in the heat for a while and they will be stuck together. Not "peel" stuck, but like the bundle as a whole will be all stuck together, only to be broken by bending the paper, and even then it is in "chunks".
Bonding: Also, when you fan through the notes, instead of them slapping hard against eachother like paper does, they appear (and sound like) they "come together" through static elec. attraction. It is very smooth and soft as they fall onto one another.
This "Bonding" factor can perhaps be explained by this: (a hypothesis at this stage)
They are paper: True
They are a different source of paper: Maybe true or false, not what I am getting at in this hypothesis
There is: some strength compound coating that has been applied somehow at some stage of the printing process, I would think after they are printed, before they are cut. Possibly during transport from final print to serial numbering. All they would have to do is insert a spray mechanism of some sort to have something applied to them at any given stage of the process.
As a result of the compounds of the coating, the electric charge given by the notes from friction would have to be different that the electric charge created by regular notes. This difference in charge would be the reason why they bond together in the different way. The application of a coating may also account for the near exact same weight, despite a thinner paper being used.
I believe that this is the case. Different paper: yes. Some agent applied to the notes for extra strength. At this point I want to mention again that in the Edmonton area, where they were discovered, I see them come through at work, all crumpled and what not, but they still have sharp edges and there is no fuzzing on hard crease lines. That is not the normal wear for paper.
Now, why then do most of the remaining notes of the $5 series come on the regular paper again? I don't know. BUT consider this--
IF you had a 2002 Journey $10 that was printed on cotton like they were at the start of the series, you would have a significant anomaly. In fact, having a cotton note that is "supposed to be" paper would be like having the 1859 1 cent struck on brass (very valuable). Or a 1944 Tombac nickel for that matter.
With that said, I leave it open for discussion about what the heck could be going on.
I disagree with many members on this subject because I believe that they are different. Despite the manner in which this whole subject came up (which has upset many people) I feel it is still in the best interest of the hobby that we try to figure this one out and find out more about them. It would be a disservice to blackball this situation just because of frustrating situations that may have arisen. (And hey I am staying away from that)
Just my five bucks-
