A base 10 with symbols only for 1 through 10, where zero is represented with an empty set is a Bijective Base 10 numeration. The columns in excel are bijective base 26.

The number of sets we can represent with fingers is 11, including the empty set.

As for bijective base 10, it's interesting, but it's still not the base 10 we're using, so we can't quite blame this on our fingers.
