I don't remember counting them, but the only ones I saw that would display
alphanumerics were also segmented, as you describe here. On display and lit
up in some store that was on Canal St. in NYC years ago, they sure aren't
there any more.
But segmented displays aren't always the best choice. If you have a display
where that last digit is reading "4" and it occasionally bobbles to 3 or 5,
a Nixie will show you this by the relative brightness of those electrodes,
while a 7-segment display will show you "8"...
