How is this achieved? The mating part is coaxial so how is it made
You can see the mismatch if you have a 75 ohm connector in a 50 ohm system
with a good network analyser-- even if the cable is correct.
As regards the original question, I'd suspect the bag to be full of 50 ohm
parts as many are coming onto the surplus market as LANs are changed to Cat5
(or 6) from the old coax based systems.
