Garage Sale Find Possible 1922 Roosevelt Perforated Error?

and yes im very aware what a hinged stamp is, but what does centering or it being hinged have to do with it being an error? But thank you for your input.

I dont assume I have one which is why I came on here to get an opinion... you guys are so quick to put someone down that your forgetting what this post is really all about. Egotistical people sometimes has there head so far up where the sun dont shine that they forget this is a place to help people that is less knowledgeable about what people with more knowledge is about. But thanks for a very welcoming attitude... your guys a very hospitable.

Outrageous.

My thoughts exactly... very much so outrageous

I provided a calm, reasonable response given the information I had- which included nothing but an image plus nothing about the OP's knowledge of philately or sense of why that particular stamp might be an error. Centering can definitely impact if a stamp is considered an error.

The amount of knowledge owned by the folks who've responded to this thread is exceedingly vast. It's import to understand the context of the responses vs. getting frustrated and defensive.

Can you please explain to me how centering has anything to do with any stamp differ it from being an error or not? I'm genuinely asking you because I would like to know.

The centering of the stamp within the perforations has no bearing on whether it is an error or not. If the stamp is VERY off-center, as in for example the perforations are 1/4 to 1/2 the way into the stamp design, then it is a freak misperforation, but not an error.

An error may be a color missing, or a different perforation than the standard issue (such as perf. 11 on 3 sides and perf. 10 on one side, or imperforate vertically, etc.).

Orstampman, in trying to provide info to the OP, I did not know how HE was using the term "error." Perhaps he thought the perfs cutting into the design was an error.

I call foul. Read this thread from the top. It took a long time to decipher what was the question was all about. Centering was entirely appropriate in trying to guess this query at that point. Even if not ultimately part of the answer. This turned out to be about a stamp that is not priced mint and is price $9500 used. What in the world is going on here?

Kenmore Stamp Company calls misperfs errors even if that is not technically the correct term.

Juss sayin....

For whatever replies were deemed egotistical, etc., I don't see it. Most replies are necessarily short in this age of Twitter and not flowery essays. Indeed, I believe we have all collectively tried in good faith to determine whether the original poster is wondering how much off-centeredness creates a perforating error or whether the reference is to the "perf 10 at top or bottom" variety. Several of us have asked for the original poster to provide the source of the "research" which leads to their conclusion that this stamp might have significant value. Without this clarification, it is extremely difficult for any of us to build on partial input and provide meaningful responses to help a beginner get the best information.

Maybe this is the perforation they were asking about. Siegel's 2019 October catalogue auction lists a couple (some top perf 10 only, others bottom perf at 10) and is shown as one of the first results in Google. Available used examples are extremely limited top error only 12 are known, bottom error Siegel has 13 and one block of 4.
