The Concorde stamp has two vertical phosphor lines running around 5-7 mm into the stamp. If you angle it to the light they will show up as dull bands compared to the rest of the stamp, assuming you do not have an UV light.
There is not a watermark.
This stamp does come with missing phosphor and missing colours but basic stamp is of minimum value and as yours is damaged it is needing replacing.
It is fluid safe if you are using plain water, no need to use anything else as it had water soluble gum.
As to the USA stamp someone else will have to comment as I have no knowledge but as you say badly damaged.
The Concorde was a joint French-UK successful failure. Successful in that it flew, in that is flew at over 1,300 MPH or twice the speed of sound and cost a small fortune in the 1970s to ride. I think it ran to about $10,000 round tip, New York to Paris, in the late '70s when auto gas was about $1.00 a gallon in the USA. It was a failure due to limited capacity, excessive maintenance costs and cost overruns, plus the need to use the few long enough airstrips and to avoid creating the famous double boom over housing.
The nose section tilted down for landing and take offs so the pilot could see the runway, and once airborne straightened out for less resistance flying.
Finally, one I can answer! The U.S. stamp is Scott no. 4018 commemorating experimental aircraft from the U.S. X works development group. It’s from 2006 for use on priority mail and parcels. 2017 catalog value for a good, used copy is 5.00 US.
There is a version issued without the X, 4018a, no value is listed and I’ve never seen one. I hope that this helps.
Charlie,
reading your reply I was thinking about US Defense contractors, glad to hear that we don't have a monopoly on costs overruns and late deliveries.

I may be imagining this, as it is from the Latin class in 1955 or '56, but I believe there is a segment h Caesar complains bout the "higher than anticipated" cost of one of his campaigns. Or it my have been the Roman Senate complaining about Caesar being over budget. Some things never end.
A long time ago and foggy recollection at best

I recently came across this stamp in a parcel I received. I know these stamps have security features but not real clear on the phosphorus feature.
I know that this is a known variety. The phosphorus missing that is. So how can I tell ?
I already had a bad incident where I soaked 2 joined 1 pound gold stamps and the ink ran.
Does this have a watermark and is fluid safe ?
Also is this a cancel from a FDC ? Thanks.
Again my apologies about the photo. The scanner is being shipped in 2 days. Thanks.
Too bad it's damaged. It's an interesting stamp but don't know much about it.
