Okay. Here is one that just sold by someone - not me - on
ebay for a final bid of $13.
The things that are most desireable on this are:
1. There is a nice, clear, easily readable postmark of the appropriate date
2. There is a nice clear dark easily readable cachet
3. The paper of the cover itself is not darkened, wrinkled, edge worn, rough opening, edge sliced off, etc.
4. The size of the cover is a number 6 which is the most desireable for any first flight cover except for those very few flights where only number 10 (legal) sized envelopes were used.
5. The cover paper is white. Colored paper envelopes such as blue or pink or grey or green, etc. are less desireable
6. This one has a big bonus of having the receiving cancelation on the front - most first flight covers have the receiving cancel on the back. If there is no receiving cancel or if the receibing cancel has the wrong date then that is a very major detraction unless it is one of the few first flights that for some reason had none of the covers backstamped - but there are very few first flights like that.
7. The return address and the recipients address are either pre-printed or typed. Very neat an small handwriting in this regard is okay, but sloppy or overly large handwriting are detractions.
8. The cancels, stamps, cachets, addresses, etc. are not overlapping. Overlapping makes these harder to read and the cover becomes a bit less desireable depending on the extent.
9. This cover does not have additional markings such as a zeppelin ettiquet or airmail ettiquet, but those are just bonus that do not detract if they are not present unless the flight had something special for it that is not present.
10. This cover has colorful and appropriate airmail stamps which is a plus. If it were a flight for which a special airmail stamp was issued then not having that special airmail stamp is a huge detraction.
I hope this helps in understanding what gets the fullest price as opposed to something less than a full price in first flight covers.
