Whether or not it is true, the following has a clear sense:
1. The Hatfields outnumber the McCoys.
(1) says that the number of Hatfields is strictly greater than the number of McCoys. It obviously does not say, of each Hatfield, that he outnumbers some McCoy. If Gomer is a Hatfield and Goober a McCoy, it is nonsense to say of Gomer that he outnumbers Goober. The Hatfields 'collectively' outnumber the McCoys.
It therefore seems that there must be something in addition to the individual Hatfields (Gomer, Jethro, Jed, et al.) and something in addition to the individual McCoys (Goober, Phineas, Prudence, et al.) that serve as logical subjects of number predicates. In
2. The Hatfields are 100 strong
it cannot be any individual Hatfield that is 100 strong. This suggests that there must be some one single entity, distinct but not wholly distinct from the individual Hatfields, and having them as members, that is the logical subject or bearer of the predicate '100 strong.'
So here is a challenge to Ed Buckner the nominalist. Provide truth-preserving analyses of (1) and (2) that make it unnecessary to posit a collective entity (whether set, mereological sum, or whatever) in addition to individual Hatfields and McCoys.
Nominalists and realists alike agree that one must not "multiply entities beyond necessity." Entia non sunt multiplicanda praeter necessitatem! The question, of course, hinges on what's necessary for explanatory purposes. So the challenge for Buckner the nominalist is to provide analyses of (1) and (2) that capture the sense and preserve the truth of the analysanda and yet obviate the felt need to posit entities in addition to concrete particulars.
Now if such analyses could be provided, it would not follow that there are no 'collective entities.' But a reason for positing them would have been removed.
I was asked this very question by a set theorist nearly 20 years ago. (Set theorists are arch realists).
Now nominalists can handle individual numbers without any problem. We point to expressions like 'a pair of shoes', which does not denote a third entity in addition to the two shoes, but rather quantifies over any two individuals.
However, "the Xs are greater in number than the Ys" is a little more tricky.
I must look at my notes.

I think your 2 is a little easier. One way, we could just have a name for every X of Ys, just as we have the name 'pair' and 'dozen', and indeed '100'. Even better, we could have a rule that allows us to construct such collective nouns, which indeed is what the decimal system is. The name '100' doesn't signify any concept to me, as humans don't have any concept of multiplicity beyond about 7.'100' is just a name that is related to '99' by the concept of adding 1. I.e. the name '99+1' signifies the same as '100' simply by the rule of constructing number names.

I think Ed is on the right track - the examples reduce the Hatfields/McCoys to a mathematical quantification. Thus, the entities are as real as any mathematical concept - which from an existence standpoint, is not very real (unless you buy into the Kantian synthetic a priori). The question, I think, is more ontological: the names Hatfields and McCoys each refer to a very definite phenomenal entity, the two different peoples that fight each other. These two complex entities contain their own unique list of predicates and produce their own real world consequences in time and space. Therefore, they are not reducible to the individual persons within the entity. QED, Hatfields and McCoys are names of real entities; or at least, entities as real as the individual members of each group.

I would say that in general we cannot analyse statements like (2) without resorting to a notion of counting. But in this case 100 can be thought of as 10 x 10, and 10 as 5 + 5, using only multiplicities less than 7, and not naming all numbers up to 100.
(1) can be explicated without counting and without resort to 'something in addition to individual Hatfields', etc. Given three empty rooms A, B, and C, we put the Hatfields in room A and the McCoys in room B and follow the following procedure. While both room A and room B remain non-empty, take a Hatfield from room A and a McCoy from room B and put them both in room C. The procedure halts when
A Merry Christmas and Happy New Year to one and all.
