Well, I found the video in question, and it is actually one of the good ones from one of the very good youtube posters, coinhelpu. The problem is, you didn't pay any attention to the information he gave except the high values. All of the coins he featured, he described well and explained why they are worth as much as they are. Nowhere did he even mention a circulated normal Bicentennial like yours. It has to be the same year, mint, variety and condition to be worth that. You need to pay much closer attention to what you are seeing if you have any hope of succeeding with coins!
