They’re all over the place. From today’s NYT, “But What Did You Do for Me Today, Developers Ask Brokers” (by Christine Haughney):
Ms. [Carrie] Chiang [of the Corcoran Group] specializes in guiding wealthy buyers through the glamorous and mundane aspects of purchasing eight-digit homes with indoor swimming pools and 1,000-bottle wine cellars.
It’s eight-digit homes ‘homes with eight-digit prices’ that caught my eye. It’s one step removed from eight-digit prices ‘prices that are eight-digit figures’ (and depends on knowing what it means for a home to have a price on it), which is still not as directly interpretable as eight-digit figure/number ‘figure/number with eight digits in it’ (though that still depends on choosing the reading ‘numeral’ for number and knowing that the figures in question are denumerated in U.S. dollars).
Eight-digit figure/number is probably to be classified as an ordinary (Type O) N+N compound, in which the semantic relationship between the second (head) N and the first (modifier) N is one from a small set of conventionalized relationships (composition, in this case), so that the compound is (relatively) easily interpreted; see the brief discussion of Goldilocks number here.
But eight-digit homes is two steps removed from this, well out into distant (Type X, X for extraordinary or exceptional) territory. Imagine trying to explain this to a child, even one who can cope with things like $34,000,000 as an expression of price.
