Jazez Hibbs was established shortly before 1899, and by 1911, they were Hibbs Ltd., so your piano is almost certainly twentieth-century. Are you able to post photos here, or email them to me?

We cannot give you a valuation of your piano here as an onsite inspection is needed to assess the condition etc of the instrument.
It would be best to make contact with a local piano tuner and ask them to assess and value the piano.
