My husband and I had our first experience with Buddy at Keystone coins. My husband inherited a coin collection from his gpa that we wanted to learn about and sell. Buddy was very knowledgeable and gave a fair offer on the collection. We will definitely be going back and highly recommend.

Saw that the price of silver was up, so decided to cash in on some estate inheritance. Had did some research and had a ballpark idea what I might get. Initial reception was warm and accommodating, I had some physical issues which were accepted immediately. Very friendly reception by all When Buddy saw the extent of my collection he recommended we sit down at a comfortable desk setting. He was patient and informative and he explained every transaction I’m 78, been around, can spot a phony real quick All indications Buddy is an honest man, providing a service, doing what he enjoys, and making a living. I’m sure he made a few bucks on me today, which he should, but I came away with over $2200 Which I was delighted by my estimate. In a day when it’s hard to trust strangers, Buddy and his crew were refreshing, made you feel they were honest, sincere people.

This is a great family-owned & operated business - the entire staff is friendly and helpful. Buddy runs this business with integrity, is very knowledgeable, and offers fair prices - especially compared with some other dealers in the Lehigh Valley.

I recently visited this shop with my mom, hoping to get some advice on preserving or grading a low-value coin that's special to us. Instead of helpful guidance, we were met with an unwelcoming attitude that felt incredibly discouraging once the value was discovered to be low. It's disheartening when a hobby that should be inclusive and friendly becomes so exclusionary. The lack of interest in helping us, especially as beginners, left us feeling disheartened and disappointed. From my personal 2 minute experience, if you don't have high-value items, it might be best to seek out a different store. Many other shops in the area I've been to are eager to chat with their customers about anything and everything, making the experience much more enjoyable. I came here specifically due to the NGC locator.
