It doesn't matter. You don't need a breaker in the subpanel (the one replacing the fusebox) at all. Anything 100A or more is legal, but the extra doesn't get you a nything.

If they didn't do it at the upgrade to 200 amps. You will for sure now need to make sure the sub panel is fed with a 4-wire feed (2 hots, neutral, and a ground wire). The neutrals and grounds in the fuse box/ your new sub panel, have to be on separate terminal bars in this case.
