Yes, it is a compass plane, probably more of a cabinet makers or joiners tool than a coopers. Both Record and Stanley made them, and probably older manufacturers such as Preston.
I have my Dads, which I think he aquired used, I think I used it once in my 40 odd years as a Joinery Manufacturer, not sure Dad used it much either. They are a nice tool, when you need one. I would imagine the value to be around £40-£100, depending on condition, maker and of course, how much the buyer wants or need it!
