What kind of knives are these and how much are they worth as a pair?

Could not figure out how to post photos here, so put them up at that site. I bought them in the 1990's. Can't find anything about the name on the blade. I'm going to list on eBay, but for how much?

I thought they were the neatest knives I had seen back then other than a scale release auto. You push on the back of the blade and slide it forward and it locks. Reverse slide puts it away. Lock is on bottom of knife. I carried a few times, but only for dress dates, no work. Thought there were too purdy to carry. Put them in the gun safe and that was that. They have been sitting for about 25 years.

Thanks

I was looking at the wrong name. When I searched for Benchmark I found some info. Thanks!
