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?
