You probably didn't see the small print at the top of the forum page which says it is not possible to value a piano without inspection.
explains that most pianos cannot be reliably dated purely on the basis of numbers. Near the bottom of the page I list some Berry numbers in the forty thousand range for that period.
Nobody anywhere can guess the value or condition of a piano without inspecting it on the spot and checking how well it holds in tune, so your local tuner is the best person to ask about that.
