Peru Sc# 1873, Fake Canecellation?

Finally, after a tense wait, my Peru stamp SC#20 1873 has arrived. I was very afraid for my purchase, since when I bought it I didn't pay attention to the seller's reviews, which, although there are many good ones, there are some terrible ones….Leaving all this dark background behind, the stamp in my opinion is great, a model that I like a lot and that I wanted to have. Although there are many counterfeits and reprints, I think from the information I have gathered and the comparison with other models, that this one is original. It is the individual stamp for which I have paid the most so far, about 40 with expenses, I don't consider it expensive or cheap, since it is a model that I like, I was excited to have it and it fits my limits. In addition, the condition in my opinion is good: it retains a great color, the printing is well executed without major ink errors that in these stamps usually leave white spaces, and both the margins and the centering are reasonable. On the downside, it has perhaps a somewhat dirty appearance, an incomplete cancellation and an excess of ink in the right margin, although the latter seems common in these stamps.
The strong and controversial point of the specimen is in the cancellation, since these stamps with the original cancellation, mark a high catalog interest. So, there are many counterfeits in this regard. To determine if it is authentic, one main factor should be given, the cancellation must be from Lima, probably stamped in the manner of: "The old genuine cancellations. which were made either from iron or bronze and which were re~used by the forgers. suffered in the humid climate from the combined action of oxygen. water and carbon oxyde. The handstamps. particularly the iron ones. corroded more or less and are no longer clearly defined. giving blotchy or dotted impressions which are easily distinguished. ". I do not have enough knowledge to know if the cancellation of my stamp was made with iron or bronze, but I will study it…and being incomplete does not indicate that it is specifically from Lima. However, at https://www.peru-philatelic-study-c...-1873-EN.pdf and in the Scott catalogue itself I have found a cancellation model, which matches one of the details visible on my stamp, a 5-pointed star. This small but very well-adjusted detail between the two leads me to think that the cancellation could be original. Although, whether or not it is original... I am very happy with the stamp and with the challenge that the cancellation proposes.

Wasn't this stamp in a different topic?

Yes, but I closed the previous one because I wasn't entirely sure that the stamp would reach my hands... I have now uploaded it since the stamp is in my possession.

Big difference between mint and used for a catalog value . .,mint it is $50.00 and used $325.00 . Thinking your going to need a cert. to convince people it is really a used copy .

Fake until certified.

The stamp is for my collection and I don't plan to sell it (unless I get another one the same or better for the same price) even if they offered me the 300 right now. The idea is that it stays with me forever...Naturally I would like to know If the cancellation is original, but not because of the economic value, but out of pure curiosity and evaluating my own criteria... probably the only way to be sure is to certify it. What do you think would be a good place?

Such a good question which points out the losses to philately that have not been replaced. Sismondo would have been my first recommendation, but he passed away not long ago. Peter Holcombe is gone as well. The Philatelic Foundation is always an option although their non-US opinions do not IMO carry as much gravitas as more specialized ones. Still better than not knowing though.

I know that stamp is real because I got the Fake/counterfeit of that stamp . The cancel is questionable but am 75% sure it is real . That is why , send it to get a cert. ,it could be worth it .

I can match that cancel to other time period stamps from Peru, that are right in front of me .

I was unable to find a cancellation with the star and double ring. Doesn't mean it isn't a later cancellation since this book stops in 1873.

+Here are the stamps I was talking about .

That these stamps have significantly more value as used was recognized many decades ago so I have to wonder why most of the ones that pop up are not on cover.

If I remember correctly, OP lives in Spain. Sending this stamp to a specialist in the US for certification might be throwing a lot of good money after bad.

@Murasama, contact CEM or COMEX to ask who would be the Spanish expertiser for cancelled Lima stamps.

Thank you all for your help!! I will continue studying the topic a little more before certifying it since it entertains me a lot and gives me good knowledge...
The truth is that the balance is 50% likely to fall to one side or the other... In favor is that it is an original stamp and without a doubt the cancellation is equally original Peruvian that could also coincide with Lima and the time, but against There is the high value of the canceled stamp, that there are many fakes and that perhaps even if it is an original cancellation it could not be from Lima...
