May I just point out that you don't always read the base of a d4 to get the number  some of them have the numbers at the corners rather than in the middle of the sides, in which case you look at the number which is on top of the die when it's rolled.

A d10 is not a regular polyhedron.

You can say that again!

When I posted my first message, I never suspected that it would generate so many responses, of such variety.
May I suggest that, with bgkdavis's learned input, and the replies it generated, this topic has more or less run its course.
Except to say again, as Tom (tchrist) wishes, that a d10 is not a regular polyhedron.

And brace you might....
I guess your real error here is the incorrect use of absolutes, its impossible for ALL dice to have sides that ad up to 7, because you are in fact only talking about 6 sided dice and have failed to take into account 4,5,7,8,10,12,20,30,100, and many other side dice.
. 
you cleverly spotted out my mistake...
oh , stepping aside from numbered dice for a moment, there is this game called "crown and anchor"  played with a 6 sided die with symbols rather than pips.
well, there is an orental version , which has gourd, castenet, coin, cockerel, prawn and fish. I 'm not shore what it's called, though

Roman Dice with 20 faces
The symbols on this die are the letters of the Greek alphabet.
It is worth noting that educated Romans could read and write Greek as well as Latin.
The purpose of this die is not known, my guess is that it was used for divination rather than gaming.

oooh I wouldn't say that the topic of dice has entirely run its course, as has been correctly pointed out there is a whole world of non numeric dice...
Interestingly a couple of people have used the D10, and D4 notation for describing dice.... I deliberatly avoided this notation because it can get misleading, as the Dnn notation refers to the number range and not the the number of sides.... there are actually 8 sided D4s, 20 sided d10s and 6 sided d3s
This means that to the pedant the repeated statement "A d10 is not a regular polyhedron.", is actually incorrect, yes a 10 sided dice is not one of the platonic solids and not a regular polyhedron, but there are actually 20 sided d10s, and a 20 sided polyhedron is one of the platonic solids
...BTW maybe I should mention I actually posses a pretty large collection of dice, at last count there were about 1,500 generic dice, and if you discount those that differ solely by size and colour I have about 200 of unique shape and numbering, and that's not including the non generic dice, ie dice that are uniquely designed for a specific game.

Not dice in the strict sense of being a member of the regular polyhedra; but I recall a popular game in my schooldays was called HOWZTHAT. It was a dicing game based on cricket, the 'dice' were two short lengths od hexagon section steel bar, one engraved with numbers of runs 0 1 2 3 4 6; the other with words describing decisions. The other requirement was a cricket score sheet. This game could be bought, or improvised by cutting up a pencil.
This is not to be confused with HOWZAT, which is an online multiplayer real action game.*

What, then, ought to be the nomenclature for the ten sided die which is numbered from 0 to 9?

One of those kinds of d10s (the singledigit, 09 ones) could also technically be referred to as a "units" die, I suppose, since it serves as the units for rolling a "d100"...not a literal, 100sided die, but two d10ss, one numbered from 1000 (or 0010 if you prefer), and the other numbered, as mentioned, 10 or 09).

I'm not aware of a special designation for a 09 D10 verses a 110.... but 09 numbering is by far the most common numbering for a D10, and you can decide whether the 0 is a 10 or 0 depending on the game rules.
As pointed out, the 1000 number dice is usually used in conjunction with a 09 dice and together they are known as a D100 , or percentile dice.
