US Modern Stamp Counterfeit Identification Guides

I started a separate topic to facilitate easier searching rather than digging through a long string of posts.

Hans van Gils has created an extensive set of guides for identifying Modern US counterfeit stamps. I know the Scott Catalog folks were very interested in working with him on future catalogs The site also has an extensive set of identification guides for many other modern US stamps.

Great idea and fantastic resource. Bookmarking this one for sure.

Amazing work! The USPS needs to use this work with AI to catch these in the mail stream. It's all free data since it's on the internet.

A few weeks ago I was finally able to get 5 fake booklets (I'd assume as they cost less than 50% face, incl. postage).
I'm trying to get a (sizable?) reference collection for booklets, unfortunately the guy was jettisoned off the bay (the Chinese do not deliver to Switzerland).

None of my booklets resemble anything in this list (which, in places is somewhat confusing).
This means that new Chinese fakes are continuously being produced (no surprise here).
