"Primus" Amber Coated Japanese 7 X 35 Binoculars

I had picked these Primus 7 X 35 Japanese Binoculars at my local auction, I had tried to see what similar items might go for on eBay, but was unable to find the exact Manufacturer, which I assumed was "Primus". It has a Sticker that says "PASSED Japan Telescopes Inspection Institute. The model number is No.69023, and is a 7 X 35 Extra Wide Angle 578ft at 1000yds. It is in amazing condition, all straps are intact, box is near perfect, and has all the lens covers. I was wondering if there would be a minimum price I should sell these for, or if they are worth keeping as they work great.
