That raises a question which I was going to ask - Is it unethical to glue the ORIGINAL stamp back onto the cover if one finds it? One time during handling a cover, one stamp fell off (not sure if it was glued properly) and I decided to remove the remaining stamps.

It sounds logical for the purpose you described. I do have a small reservation on this though. If a Qing Dynasty cover has glue that belongs to 21st century provided that someone needs to lift the stamp(s) then put it(them) back in order to verify something, would it hurt the value of the cover a little bit?

I guess if we follow the process of a typical antique restoration then this is not an issue. Is this considered as a process of restoration even if the cover is not damaged to begin with?

請問為何不裁在線上? 這是由不同機器裁出來的嗎?

感謝您的解說.

Agreed with the concept of "value and "price". My instinct tells me that most people would not attempt to perform such task. In some cases, certain value may overwrite the importance of finding whether the stamp carries watermark or something else.
On the price side, there are cases that one can increase the "price" of an antique if it is properly restored. Other cases are completely opposite when not done properly - polishing an antique made of brass for instance. In the case above, one must accurately reposition the stamp that was lifted earlier. Now how accurate is considered accurate could be very subjective.

I'm glad that we have this discussion. Collecting stamps is very subjective while selling stamps needs to be somewhat objective.

此封為帶版號捲筒票集郵實寄封(明顯是故意貼的). 每張郵票皆是帶版號票.此封沒什麼價值因是作封且郵票都是單枚. 噴碼擋住三枚郵票加上收件人住址可能寫錯用貼紙貼上再重寫.
目前帶版號捲筒舊票價碼約一元台幣一枚初集者可從此開始.
請問一件自然封的客觀品相如何打分數?除了郵票品相,郵票位子;戳品相,位子;封品相;住址是否清析;郵資是否符合(假設以上個項都沒什麼特別) 還要注意那些?

看完此書最後一章才知道在美國郵票假造或改造與鈔票一樣, 是歸 Secret Service 管的.

假造或改造郵票圖利的罪與鈔票一樣, 屬於重罪.

感謝tmh前輩的解說,小弟還有一個問題.
這捲筒票封存在的條件必定是集郵封, 因按機率, 自然封是不可能的. 說實在的小弟還希望只有數枚是帶版號而不是全部.
近期的封, 自然與集郵封在收集上可能差別不大, 因數量較多.
早期封對小弟而言頗重要, 因自然封是小弟收集的重點.
當郵資,戳及其他因素都正常, 每次只要看到有整套郵票貼在封上就覺得不”自然”, 不是心目中的自然封. 這觀念是否要改?確實有貼全套郵票的自然封只是不容易判斷,只有寄件人知道.

感謝tmh前輩的意見.
小弟收集自然封的範圍很狹窄所以遇到類似不易得的封當然先求有,就不會計較那麼多.

1930年代初期, 一位中年婦人走入美國西部一個小鎮的郵局.
“請問膠液可否借用一下?”
承辦人員把膠液遞了過去同時注意看著婦人把兩張看似未使用過的郵票貼到一個厚重的包裹上. 接著婦人把包裹交給郵局承辦人員.
“請付40分郵資”,
“為何還要付40分?難道你沒看到兩張20分郵票貼在上面?”, 婦人怒道.
  “我看不到” 承辦人員答道,
“包裹上什麼也沒貼. 因為這兩張郵票是使用過的. 我建議妳買兩張20分郵票貼上因為使用過的郵票若再貼用是要罰一百圓的.”    (註:當時一百圓可不得了)
婦人很不高興的掏出40分交給承辦人員然後離開. 承辦人員馬上把包裹上的郵票拉起然後丟到垃圾筒裡. 就在他重新將兩張新郵貼上時他忽然聽到有人很重的把門關上的聲音.

以上節錄自Linn’s Weekly Stamp News, Oct 12, 1935.
註:此郵票新郵是有膠的.使用過的郵票就算未銷戳而再使用也算犯了postage revenue fraud.



在美國網路上有時會看到折價拍賣大塊高面額無膠未銷票, 您若購買然後貼來寄東西Secret Service可有興趣約談您.
以1930年代那時美國的法律連收集假郵票都可能面臨牢獄之災. 現在只要沒有獲利企圖應不會有問題.

清清之前這裡有談到造假及改造郵票的郵政法規. 以上這個case在台灣算犯法嗎? 有人會問怎麼證明票是用過的?小弟相信當Secret Service找上你您時, 他們早已有科學的證據.

註: Secret Service在1901年前專辦偽鈔及偽造有價證券重大案件.1901年William McKinley總統被槍殺後國會授權Secret Service來保護總統.
