Nice little shop with a vintage touch

The coin dealer in Walnut Creek provided solid service. They answered my questions without rushing and handled the transaction smoothly. I couldn't help but notice a vintage model airplane sitting quietly in the corner, which was a nice touch during the visit. Overall, reliable and straightforward experience.

Really smooth coin buying experience

Wow, I never thought buying coins could be so smooth. Almost got me thinking it was too good to be true but nope, legit and friendly service all around!
