They were average commercial pianos, by now very old, and likely to suffer problems, especially loose tuning pins. Here in the UK, pianos like this have very little value.
Serial number dates are not available. The retailers, Teague & King, became a limited company around 1905, so this piano appears to be before that, but we can't tell anything about the individual piano without seeing what the WHOLE thing looks like.
