Joe (harvey), I had my stamps looked at by members of the American Philatelic Society of America (in Florida), when they had a display at the APS annual show in SF (circa 2015 I think). (This was truly an amazing collection shown, and I seem to recall an article about it in the magazine?)
These guys are real expert, and they went through my collection of nearly 25 Puerto Principe stamps (my wife had purchased for me a very old album in the street market in Havana years before, which got me started collecting Cuban colonial stamps).
Not one of my stamps was real. Every single one was counterfeited.
Furthermore, there are so many varieties of the overprints that I have no idea how they go about telling a fake from a real o/p!
There is also another group in Florida with strong expertise: the International Cuban Philatelic Society, and I have had some discussions with them as well. Here is a good reference to one article of interest to you: http://www.cubafil.org/MemberPages/Ortiz/PuertoPrincipe/Ortiz-Puerto_Principe.pdf
This is one of the best illustration rich description of the O/Pp but alas, it did not give me a clue on identifying the counterfeits in my stamps.
Ernesto Cuesta is an expert I had spoken with in the past.
My suggestion is to contact these two associations and get some help, but my guess is that 99% of what is still out there circulating, unless with certificate, is fake.
I still look at filling missing gaps for the fun of it, but I will only pay a token dollar as I am sure whatever is out there is fake. With certificates, these stamps are quite expensive.

Another set of problematic O/P for Cuba are the 1883 set. These are more affordable but also a problem to identify. Note that Fournier issued counterfeits of them, among others, and he also issued counterfeits of the 1996-1998 stamps.
If anyone is interested, I will scan my pages of the Cuban 1883 O/P.

I'll read the articles, but it's a real shame that so many countries have so many fakes! Two of my four major areas, Cuba and Poland, are a major problem!!
A dealer I get stamps from on a very regular basis sent me three of these hard-to-find stamps and charged a very low price since he couldn't guarantee the overprints are original. I've checked on line and the few fakes they showed had very smudged overprints and I doubt if this is always the case. Is there any sure, or almost sure, way to tell? Can anyone direct me to an article or book that shows the difference? Or do I have to pay for authentication with no real guarantee that that person knows what he/she is talking about?
Edit: My gut tells me to treat these stamps the same way I treat the early Poland stamps - exhibit huge skepticism and pay as little as possible!!
