Hi Swift,

Thanks for the advice. I have the similar experience you have and I took some lessons on that. Now I don't get that excited when I see something rare. If it is too good to be true, it probably is. Your advice is very valuable to me.

When I purchased the lot, the seller did not even show any of the covers. It's just a box with all kinds of junks inside. If we just look at the stamp without the cover and let's assume that it's been altered, why one would alter it like this? That's my question. If it indeed is mis-perforated, one could have just torn the stamp at the perforation location and it would have retained some value. If it was imperforated, then some idiot must have done something to the stamp. These are the logics that I can't seem to be able to put together, not so much about "value".

So if we just discuss the stamp itself, we know the fact is there is no perforation on the left - that's all we know. Those cheaters would want to alter the stamp to increase the value not make it worthless. In this case, they made it worse if the stamp has been altered in my opinion. What do you think?

When I posted the picture, I was expecting someone would question the stamp and explain what happened to the stamp. I guess with only the picture here, there is not enough information to make a conclusion. All we know is a cover with a question mark.

I actually planned to remove the stamp and place it on my album (I've done that many times since covers take too much space) but now you make me not to do that.

I hope such discussion will provide some help to the viewers.

Hi Swift,

Thanks for spending time analyzing this for me. As you know, this type of bullseye cancels are very common and hence are one of the popular ones that cheaters like since one can replace the stamp on any covers without a chop mark.

I do have some oddities. Like some collectors, I usually make a story next to the stamp regardless it is true or not. This one will go like this,

1. The stamp is likely a mis-perforated one to start with.
2. Someone tore the stamp inappropriately and made it unattractive.
3. Some cheater made a straight cut on the badly torn side and replaced the stamp on a used cover to make it attractive to buyer.
4. I'm the buyer!!!

Case closed.

tmh前輩,
1.    記得有每捲有分100, 500, 1000, 3000, 10000枚有些500枚以上的還有背號(back number)用來清點還剩有若干票. 至於背號系統每家私營供應商都不太一樣.非自黏郵票直接印在背膠上.
2.    單色票二位數版號最高為22
3.    若為多色就不一定. 如數量龐大的SC#2915A  1996年版國旗票有五色, 版號可有99999, 每個數字代表顏色及印筒號. 但也有A88888. 這A(B,C,….)代表此票是私營供應商印的而非 國營Bureau of Engraving and Printing (BEP).
4.    99999後為 11111A, 22222A來避免用二位數代表單一顏色及印筒號.
5.    收集以全套為主如某票有版號1,2,3,4,5,6那這6枚就是一套
6.    PNC的編碼系統可參考此網 (想到鐘火盛前輩的郵檢戳)
http://www.usastamps.com/references/PNC_Catalog/Numbering_System/Basic.htm
7.    其他請參考此網址(excel檔案). Scott的資料大都在裡面 點PNC DATA再點PNC MASTER LIST - BY SCOTT & DENOM.裡面有Excel file可下載.有這檔案就夠一般收集了.
http://www.pnc3.org/
8.    捲筒轉一圈印一次版號. 最大筒為一圈52枚
9.    有買相關書籍但一時找不到
10. 早在1981年以前就有版號,只是位於邊緣,在過程中已被裁掉..有少量趣味品還可見半個號碼甚至整個號碼(誤裁).只是手上無貨,無法舉例.所以嚴格來說,1981年才有正式發行的帶版號捲筒票.

集新票只能買整捲很浪費錢.
集自然封若在公司行號上班,能找到PNC5大約每30封五橫連會有一封.郵資當然要對且版號要在中間那枚.一般收集人不喜歡看到有1980年之前的郵票混在裡面(有作封嫌疑). PNC3, PNCS (PNC1)相對收集較易, 至於PNC7以上就要看運氣.
小弟已有一段時間沒碰PNC了主要原因是網拍自然封價格不便宜(以小弟的標準). 或許在台灣可撿漏, 因集這個有點冷門.
以上是靠一些記憶,還請先進指正.

此封從葡萄牙1991年1月11日以航空掛號寄出. 貼了兩張小全及一些散票,判斷是集郵人士寄的.背面銷了八個戳. 國外戳不談, 國內銷1月17日台北未37戳3次(可能第一,二次銷的不清楚), 18日再銷一支甲戳. 查鐘火盛書, 時間與戳型(最晚民國77年12月,晚幾個月或有可能,但差太遠,戳為W型)皆不符, 所以應是郵聯戳. 背面又貼一張中文籤條(箭頭處,已被撕去)
請問前輩為何銷未與甲戳? 一支甲戳應是多餘的吧? 籤條功能又為何? 用來簽名?在美國是簽在另一張卡上.
正面”航空”二字是個疑點,是貼上去的紙條. 未戳有可能是假的嗎?仔細觀察兩個未字不太一樣.

謝謝tmh前輩的解說.

請問這是南投縣埔里鎮蜈蚣里嗎?從來不知有此地名.

Flying geese overprint cover.

Franked with two one-dollar narrow-space Flying geese overprints (1st print), 5 cents Northeast 44 dollar surcharged and farm product 10 cents surcharged , tied by TAIPEI CDS of 1950.1.5
Cover was sent to Hamburg Germany without arrival CDS. Stamps were on the back side of the cover - bad idea.
If the CDS was 3 days earlier, it would have made this cover very unusual. At least, it was used during 'that" week. There is a cover in Paul Chang's book shown the exact date but that cover is way better than this one..

P.S. 1950.1.1 was Sunday.

Sorry, this is a duplicated page. Deleted. 

Hi Swift,

Nothing can be hidden from a Pro like you.

I did send a message to the seller asking about the void area and a possible missing stamp before I bid. The seller replied "bid accordingly!". I got it at relatively low price. Guess a lot people noiced that too.

Since the cover could be an eye sore to someone, is it better to remove the stamps and put them in an album?

Sorry, this is the second time I asked you the same question.
