In the mid-80s, my dad would often go to this place that was sort of a pawn shop / antique store in the bigger city near us. I quickly got bored of looking at the same old records, antiques, etc. each weekend, but became fascinated with this smaller, locked area where they bought and sold old coins, PMs, etc. I remember going in often and buying
Mercury dimes for 7x face value. As a youngster, I couldn't afford many quarters, halves, etc. at 7x face, but I could always scrounge up a couple of bucks and get some sweet Mercuries for my every growing album.
It just expanded from there...family members would bring foreign coins back whenever they traveled, I would dig through change looking for wheat pennies, I even started searching nickel rolls from the grocery store's customer service booth, keeping anything pre-60s. It was fun until around high school time and then priorities shifted. I would always drop back in now and then when I'd find something interesting, but it wasn't until a couple of years ago that I really got back into coin collecting.
