It appears to be oak rather than mahogony !! I have not seen one with those details but if you have looked on the website and can find a similar one,, that is what I would go by as a selling price !! Just because it may have different styling than the ones you found,,the price would not vary much !! I don`t think yours is a particularly early one,, perhaps 1920 or so !! Of course I am going by the overall style of it since we can`t see details !!
