1879 S Trade Dollar That Was For Sale

Crusing Craigslist I find an ad for old currency and coins. On the phone he says the coins and currency are in great shape. He agrees to meet me in my town that night. The guy didn't know coins or currency. The silver certs were ripped torn folded and/or dirty. His Winged Head Liberty dimes were VF at best. The "Wheats" were VG-VF. Then there was an American Eagle and a 2000 Proof Quarter. Some interesting errors were there also. Now about the 1879 Trade Dollar-I don't have my scale with me and I want to check in more detail about determing if it was real. I called him and we couldn't agree on the price of his melt silver. We agreed for me to come over to his town to look at some tools. Someone else saw the ad and went to see the coins and currency. He looked and and they did the what do you want-what will you give dance and the buyer offered $600. A supposed very, very rare coin in a plastic snap tite, not a 2x2, a little nicer than that. People don't let your heart kick your brain out of gear. There were replicas made that weren't stamped replica. The chances of that buyer getting the real thing are slim to none and the money is on the none. Caveat Emptor-LET THE BUYER BEWARE!
