Seeking Opinions On Paper Type...

Soft and soft.

Thank you... last time I tried this, our moderator moved my posting
to BOB before the discussion could get this far...

I've been trying to decide if it's worth it to send both or just the
stamp on the right to the PF for possible ID for J10 (soft porous) vs J3... (J3 paper type is not enumerated in Scott)

In the ensuing discussion (in BOB) it has been suggested the unused
stamp to the right could be a J17, which I hadn't considered...

Your thoughts?

Somehow, I don't feel the color is right. See attached photos from Siegal Auction.

Given that the J10 is the rarest one in all the special printings, I think the chance of winning is slim. But I don't think you will lose much by sending it for a cert. If it is J3, you got a cert at a cost of say $50? But you can sell it in the future at a little bit higher price. If it is J10, then you pay a lot but will sell it at a much higher price. I don't think they will charge at a J10's price if it is indeed a J3. So you will lose say $20-$30 at most? But you may have a chance to win $2000. Ok, ok, it is a gamble, I admit. But it is fun. LOL

Tang... at this stage, I believe J3 would be ruled out, given the
paper type as soft porous... 10 & 17 are both soft papers, so the
cert will land on one or the other...

I have what I believe to be J1 and J2 in my collection, and the paper
is firm, like hard papers, not soft and pliable, as are with these 2
stamps...

The thing that lingers most in my wonderment is the brownish tint to
the paper of the unused copy... I'd doubt the paper was that color at
the time of printing, so some sort of bleeding had to have occurred
somewhere along the way...

Your thoughts?

I find this thread interesting in the fact that the OP is presenting theory, which he may be correct, that early postage dues can be classified based on paper type (like large banknotes) rather than relying on ink (fluorescent vs no fluorescent and of course, color)

I have not heard of this but he/she could be correct. It would be much easier to hold up a stamp and determine paper type and say it must be J17, not J3, especially to a guy like me with some possible color blindness. I generally despise postage due stamps because I cannot determine the vague color differences required for classification, but if paper type comes into play, this could all be easier.

But honestly I have never heard this before. Any early postage due experts out there????

To continue,

My impression is that all of these stamps are soft porous produced by American Banknote Company, including J3.
Did American use hard paper in earliest stamps before switching over to soft paper?

J17 is quite a rarity as well and there is backstory here on why this stamp is valued so high compared to The other red browns J15-21. This has been discussed previously.

I still agree with others that your stamp looks more like a J3 from color standpoint.... but if paper type is a huge factor,in classifying these stamps..... someone please educate me. Brown ,red brown, claret deep brown., deep brown, deep claret .. just shoot me

The first post was moved to Back of Book because there were requests to do so, obviously we cannot please everyone. Cross posting, which is posting the same topic in multiple threads is against the rules. The rule is there for a reason, so that everyone can follow the topic in a single place, reduces clutter, and it especially helps when user search on the topic in the future.
