The clock in the picture looks like a "Split-column" clock made by the Seth Thomas Clock Company somewhere around 1870 - 1890.
They evolved from Seth Thomas' long time standard OGEE clock and have the same movement and weights but the case was dressed up a little with the columns for the higher priced market.
I have sold these for $250 - $400 depending on their condition. Of course they are worth more than that if the condition is all original and mint.
