Alex was a pleasure to work with on several visits. He took the time to explain the difference between coins with collector value vs those with precious metal values. His pricing was fair and the process couldn’t have been easier from appointment to sale. Highly recommend!

I had a very pleasant experience at Harford Coin. The owner was extremely knowledgeable and explained a lot about the coins I brought in to be evaluated. I also very much appreciated the appointment only system as that gives the owner and the customer ample time to go over any questions and make any decisions. Highly highly recommend and I will definitely take my business here again. I also got a very fair price for my coins.
