Have you determined their watermark yet? It should be easy with a block of four. Aside from that the only difference would be color. To me they look to be the more common color, but the internet is not a reliable way to verify what color stamps are.
Thank you for the feedback, I’ll look for a watermark to verify them.
Are they somewhat rare because they were printed sideways?
I think I may have some too.

Who is Mr. Teisler??????

I haven't come across any other sideways stamps in my collection yet, but I will keep my eyes peeled for sure!

So I found the below set of 1 Cent Postage Due stamps in some unsorted ones I have. A quick search on the internet said that these may be somewhat rare. How do I verify if they are real or not though? Any help is appreciated. Thanks.
