I wanted to bring up a recent purchase at the only coin shop in town where I live. It put a bad taste in my mouth and I will only buy junk silver there moving forward because of it. The owner knows me pretty well and I have spent thousands of dollars there over the last few months but we recently had a disagreement that I wanted to see if it was common practice. I have never seen him buy coins before from others but he buys them based on the lowest grade of the coins side minus 1 grade. So if you have a AU50 on one side and XF40 on the other, he will pay you for a VF20. Seems fair to protect his purchases and grading should be based on the lowest side. Granted, if there is a large discrepancy between the minus 1 grade, he won't go the full grade. That wasn't my issue. At the time of the incident, he bought a group of Peace Dollars, so I was interested in repurchasing some of them like a fish on hook. We ended up talking about A, B, C non-sense for an hour and I think he forgot I saw him purchase the coins. He turned around and told me he was selling the coins based on the highest grade side of the two sides, not the average of the two sides and not the weakest side. I really was put off by that because some of the coins had beautiful reverse sides (AU 50/58) but then the obverse would be XF40- or VF20+ with deep or plentiful scratches. The final kicker was when I noticed that several of the rare coins (1921 and 1928 P/S) had been cleaned as they had several scratches all in the same direction in a circular pattern. Granted, you could only see it under strong light but still, they were cleaned and not AU 50/58. I ended up not purchasing any of the Peace Dollars and just bought a bunch of junk silver at good price but wanted to see if this was a common challenge with coin shops as I hadn't had this problem before. I couldn't take photos unfortunately because he has a strict no photo policy.
