Karl is fair with pricing. Will explain throughly what the value is of your coins. He is not pushy and will wait for you to make decision. I recommend you see him with your gold and silver.

First time going to Karl's or any coin shop, and he welcomed me in and helped me out with the coins I brought in. I was really appreciative of what I got. This is the one you need to go to, ladies and gentlemen; you won't be disappointed. I'm definitely going here when I decide to sell more coins.
