We were pleasantly surprised walking into Eagle Coins and meeting Ed. Sometimes you just know when you can trust someone and this is exactly how we felt. Ed and his wife were so gracious as well as knowlegeable. Got a great price for the gold we sold, and will be back with more. Read more

Just went to sell some coins and wasn't expecting much. The owner Edward Guariglia was so nice and so kind. Very fair price and didn't make us wait. Another plus he fixed a broken necklace that I gave to my husband who has passed for free. Such a positive experience I will definitely be going back. Thank you Ed. Read more

What a beautiful Saturday experience! My friend and I were warmly greeted by the owner’s wife. Right after we were offered a warm and delicious coffee while waiting to meet the owner. All smiles during our entire visit! It felt like a doctor’s appointment with the owner being so considerate and following through the entire conversation my friend and I had with him. Five plus star customer service! We will definitely visit Harwich again. We wanted to make a new friend today and it looks like we did. Thank you to all! Read more

This was one of the best customer service experiences I’ve had in a long time. They were incredibly kind, patient, and genuinely made me feel taken care of from start to finish. I never felt pressured at any point, which I really appreciated. Their prices/offers were fair, their communication was great, and they truly went above and beyond to make sure I was comfortable and happy with everything. You can tell they actually care about their customers, which is rare these days. Highly recommend. Read more
