We all used to collect baseball cards and all that jazz. I grew out of it but many people continued. I have a friend that scavenges garage sales, and uses a pda to price everything there with a barcode. Actually makes good cash for bumming around on weekends at garage sales and amazoning during the week. Well we were talking about our old rookie cards and this and that and it came up that in every box of Topps or Fleer special cards 1 pack contained a special card with a jersey or rookie on it. Well the scam was people were going to places that sold the cards and were weighing them with digital scales to find the 1 pack .01 grams heavier. Thus that was the pack with the special card. Not sure if people caught on or howit works now but people used to actually do this stuff.
