Lincoln Commemoratives 367-369

Where should I look for documentation on the bluish paper used for US Scott 369? I have 367 and 368.

As I search around looking for options to buy 369, some of the vendor photos def look bluish. Others, not so much.

I want to understand how 369 occurred and why, but I also what is going so that I know what I'm looking at and what to look for.

General interest but also be an educated shopper.

Here's a link to an APS Library where you can do a search for results for "bluish paper."

Search for 'bluish' on this forum and you will find a few threads. This one is probably the best, showing a few side-by-side photos and some good background details that you are asking for:

The discussion is mostly around the 357-358 Washington Franklin stamps, but the same information applies to the 369 Lincoln as well.

The best way that I have found to identify them, place 1 (or more) regular stamps from the same series (e.g. #367) face down on a piece of orange paper, along with the candidate #369 face down, and the difference should be obvious.

If you are buying online, buy from a reputable seller and one who takes returns if you don't like what you receive. In my opinion a certificate is generally not necessary (not worth the cost) for a #369 unless it is in excellent condition and gradable, but it certainly doesn't hurt to have a certificate if you want good peace of mind.

I agree there are lots of sellers who offer faded or toned stamps as if they were bluish paper. A certificate is essential for any of the higher value bluish papers #359-#366.

The bluish paper is actually greyish

Thanks so much. All great information that is already answering my question, and I'm going to make use of doing my own searches as well.
