Some Classics From Colombia. Fakes?

Hello,

I've been digging into these pieces lately but I'm just starting to learn about Colombia pieces... so basically testing my findings so far.

Let's start with Conf. Granadina pieces.

First picture. I feel confident about these pieces except the 5 cents in the bottom right. Is that a pre-philatelic Medellin Franca cencellation?:


Next in line... Again, most look good to me, except the top right and bottom right pieces.


Third picture. Are those good cancels? Again, that 1 Peso is suspicious to me... what do I know:


Ok... I'm lost on this one... I'm afraid they are all bad :( Please, tell me I'm wrong:


I'm pretty confident on this set. They all look good to my untrained eye. Is that red zero on the top right any special?


And finally this one for now. Again, mostly confident... except for the 1 PESO in the top left:


What do you folks say? Any special mark? Thanks in advance!

By the way... special thanks to Jerry for sharing his excellent documents (Identifier.docx was super useful!)

Hi Will

First off: Do you speak and/or read Spanish?

with a subject of "Colombia" Stamps. I'll transcribe Barriga's notes on these issues and send them to you.

Will,
You do not yet have enough posts to allow other members to message you but in this case I am willing to act as an intermediary with Jerry if desired. You can contact me using the Stamp Smarter contact form.

Hey Jerry, I do. and we know each other in real life :) You just don't relate me with Colombian stamps. Understandable, it's totally new to me. A good friend in Venezuela died and I bought his Colombia collection from his wife. The collection seemed good and pretty complete, including states and some nice air mail stamps (and a 6-18-1919 cover with a type 10, which I love!) but you know my allergy to fakes so I want to make sure I can catch most if not all of them.

I followed your advice and grabbed a Barriga... it hasn't arrived yet. The Temprano did though... and I also followed... Timm's advice? and bought a copy of the Vol II of the other book (was it The Workshop, Notes on Forgeries [...]?) It hasn't arrived yet either... Let's see!

Again, thanks for sharing your notes. They've been very helpful.

Don: Thanks for volunteer. However, I rather keep all the conversations in-forum so future readers can, hopefully, benefit from constructive conversations (as I've been doing.)

Hi Will

I am assuming that the name Castillo has meaning. Hint was Venezuela.

Take a look at this site:
http://stampforgeries.com/forged-st...a-1859-1869/

I don't know how useful the site is as most forgeries are not described. However, there may be something useful. Another site is:

http://www.fipfakesforgeries.org/fip/?page_id=166

You may need French on this site. (I just found the site).

What year Barriga did you get? Hopefully 1980's. The new ones are not very useful.

Don: Thanks for the offer as intermediary. Since I know this person there is no need to intervene.

Yes, it rings a bell.

I've also used StampForgeries.com... It's a great resource as well! Given that I'm used to identify fakes and forgeries from Venezuela, the (general) lack of descriptions was not an issue.

And thanks for fipfakesforgeries.com... didn't know that one.

I got a Barriga 1982.
