So guys today I sold a lot of my silver coins .4 lunar mice 5oz silver,5 2019 panda space blue, and 1 2019 guided kangaroo. I had my lunar mice listed at $250 each because the mint is down and I seen them listed for $285 on eBay from a guy named silver Kev who has his own channel and seems pretty knowledgable on coins .So I took the price down and thought maybe $250 is a good price. Long story short the guy haggled the price down and got all my coins for exactly what I paid for them which was 4 x $165 for lunar mice and 5 x $165 for panda coins and I threw in the kangaroo and sold him some police $2 coins for $75.I paid $89 for them. Then I get home and he messages me telling me I'm some guy on gumtree ripping people off when the last person I sold coins to was all my silver eagles which I sold for $37 each then threw in one because I wanted to be nice. So anyway the guy was upset in messages for a bit and then said it was his fault he should have checked. But I just feel terrible now . Like I don't want to be known as someone who scams people but I really thought the lunars were worth a bit more just because everyone else was selling them for higher and because mint isn't producing them anymore. I was just really happy that I sold the coins cause I was going to buy some bars but now I just feel like shit and wonder why I always have problems letting things go. Everyone is telling me he bought the coins and he should have known what he was buying but to be honest I made no profit on them at all. I just feel like crap now .
