Need Help With These Stamps Please

New to stamp collecting. Found these and need to know what they truly are. I have been told so many different things. Thank you

Third repeat thread: https://goscf.com/t/91555

Just trying to get someone who knows what they are. Seems no one knows what they are. I have looked everywhere and can't find these. I can't understand why no one can identify them correctly. Every answer is different. I have acquired a very large collection over the years with a lot of stamps like these. I thought I could get the real answers here because someone directed me here. Craziness. That's why three and still haven't git an answer. Thanks for the time.

By cross-posting, you are breaking the rules of the forum.

You got answers in one of your other two threads. The CTO block has an utterly common misregistration of colours. The single has a minor misregistration of the central vignette. Neither is an error. They are minor varieties and from this country highly suspect.

I agree with another poster that you should ask the person who mentioned the 400 why that is. Also, ask him whether he meant pesos or dollars.
