Matt Lerner

Owner of Frederick Coin Exchange


I started collecting coins when I was 5 years old; and fell in love with the hobby. My mom used to drop me off at a local coin shop and I would spend hours and hours there, until one day, they asked me if I wanted to help them out in my free time. How could I say no? Well, I was 11. So they couldn’t really ‘hire me’ but could give me free coins in exchange for helping them out. In 1999, when I was 13, I was introduced to eBay. I started out selling state quarters for .99, plus .49 for shipping and handling (of course). I’d ride my bike to the post office and away went the coins. In the beginning I did it to make enough money so I could buy the coins I needed, when I graduated from high school I decided coins would be a great way to help pay for school and got more serious about the business. I applied to 12 different schools all over the nation. The first school I visited was the University of Wisconsin-Madison. I fell in love quickly. Not by the academics, not by the campus, but by the fact that there were five coins shops within 15 miles of the university. I quickly sent in my acceptance and began to network with a local dealer. Soon I became the ‘go to’ buyer for all of the local shops, buying their excess inventory and selling it to dealers and collectors all over the nation. I graduated in December of 2007 from the University of Wisconsin-Madison with a degree in marketing and decided pursue coin dealing full time. I opened my first physical retail location where I grew up in Frederick, MD in 2009. We’ve become one of the most competitive coin and precious metals dealers in the area.
