Due to the scarcity of N*000 numbers, we sometimes offer numbers that use 'Q' to view as 0.. as in the Falcon 9000 registration pictured here (N900Q)
The same applies to numbers that have Ks to view as Xs. With a clever choice of FAA approved fonts and placed strategically, they can look excellent to the casual observer and are great value at about a fifth to a tenth the price of numbers using real X's. I saw the Global Express s/n 9108 at KVNY, it had the registration N700EK [for 700EXpress] very nicely done, but so far I haven't been able to find a photo of it. If anyone has one, please send it in, I'd appreciate it.
8's and B's are almost identical as seen here on this Bell 429
The number 5 and the letter S are almost indistinguishable, as apparent in this image below.
