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.

We brought in a largely inherited coin collection. Owner was very knowledgeable, patient, explained why they were or weren't valuable, gave us what seemed a fair price on the spot.
