Since I'm new to this, I went with the vernacular.  As a coin collector, the glossary is a lot less in volume.  Now I am wondering about value.  Would the one on the right be worth more? And what would be that worth?  I now it's about what a buyer wants to pay, but is it like: A standard Akro corkscrew is worth $X, so the one on the right is worth $X + a small premium?
