Curious About These Any Knowledge

It would clarify fully to myself and anyone who made read this
And hopefully prevent another repeat question about it
As confusion in comparison happens

I do truly appreciate all the replies
I came here for help
I don't wanna seem ungrateful for any information
I mean I may have asked an apparently foolish or joke
Question by asking if it was the same
But I haven't seen the other up close just pixel distorting screens
And detail is important
I mean I'm sorry if I question
But with the pictures I was looking at there seemed to be a difference

You're mixing up a number of different things:

A) The secret marks are part of the stamp design itself, not the overprint.

B) The catalogue pages you're looking at show secret marks for a different series of stamps than the one that Vayolene posted. That's one thing perf12 was telling you.

C) The differences that you see in the overprint are caused by differences in the amount or quality of the ink used. They have nothing to do with secret marks.

In general, consider buying a newer copy of Scott's Catalogue. You can find them used on ebay for relatively little. Newer editions are easier to use and include color photos that help a lot. And do figure out how to post a photo upright, not sideways. Good luck and don't give up.

Thank you

I realized that the secret mark was a different stamp
But I asked if there was a difference are they exactly the same as stated
A simple yes they are all the same there is no differences in year,issue,office policies political reasons Nothing like that
it's just a simple worn out stamp and watery ink
With again a photo reply would be solid

I thought it was a simple question are they different?
A yes they are the exact same and even if they aren't
There's no relevance or history behind it at all to bother
Just a minor detail to the overstamp
Easy enough apologies
Being new at this I guess I ask a dumb question the wrong way

I think you're still confusing secret marks and overprints. Those are two entirely different things. All your photos are of overprints, and they have nothing to do with secret marks.

A) Secret Marks: Only a few Chinese stamps have them. Of those that do, different issues will have different secret marks, and within an issue stamps with different face value may also have different secret marks.

So, if an issue has secret marks (e.g., the Martyrs Issue of 1940-1) you must take stamps from that issue and compare to one another only those that have the same face value. Then you will find that both have the same secret mark: exactly the same. It's either there or it isn't.

And where is the secret mark located? The stamps about which you're asking are from the Martyrs Issue of 1932-4, which does not have secret marks. But those stamps were re-issued with secret marks in 1940-1. For that re-issue the secret mark is located in the left Chinese character in the bottom row of the original stamp design (e.g.,next to the 3 or the 8). The catalogue tells you that. But you're looking at the left bottom character of the overprint which, as I say, has nothing to do with the secret mark.

You posted a photo of a catalogue page that shows secret marks. But those marks don't go with the Martyrs Issue stamps. They go with the Sun Yat-sen Issue of 1939-41. The secret marks for the Martyrs Issue of 1940-1 are shown a bit farther down. Again, the catalogue tells you that. Just read it more carefully.

If one stamp has the secret mark and the other doesn't, the latter belongs to a different issue that doesn't include such marks (e.g., the Martyrs Issue of 1932-4). That's so also if neither has a secret mark. But always compare only stamps of the same design.

B) As for Overprints: They're added later, on top of the original stamp and, I say again, the overprint has nothing to do with secret marks. The photos that you've posted are all of a portion of the overprint, not of a secret mark.

Now, there are many different types of overprint, for many different purposes. Even stamps that are otherwise identical can have different overprints. And sometimes, even when the overprint is supposed to be the same, it may differ slightly because too much or too little ink was applied, or because the printing plates had begun to wear out. This is what the others have been telling you in their responses so far.

Finally, your question isn't "dumb." You just haven't asked it clearly enough. (And please, stop including Lmao.)
