Brombal Paul A Coins & Jewelry

As soon as I arrived, he (Paul, apparently) was instantly short, and exceedingly discourteous. I had brought coins for appraisal and potential sale. He LITERALLY flung each coin I set up on the counter off to his little tray, with two or three words of what worthless coins they were. I realized he wasn't even checking dates, mintage, condition, anything! Even with PCGS rated coins! So I put up a Silver NGC grade PF70 Silver Buffalo. A very desirable coin, worth $100+ wholesale. He looked, flung, and said any of this silver is $2 over spot (spot=$18 now). What a dishonest jerk. I asked, even for a proof Buffalo? "It's NOT" he said. I asked what does "PF" stand for, and pointed. He looked, got angry admitted it WAS in fact a PROOF, but he then didn't want any of them. He told me to accept anything over face value on all my other stuff!? I have a MS68 1943 steel penny worth $50 if it's worth a cent, and he said that if I could get two cents for it, I should take it. THE WORST SERVICE EVER
