Sad to see some of these responses, it guess it just shows the integrity and morals of people. I bet they never had anything stolen from them of any value.
When my cards got stolen I called around and within 1 hour, I found them, every dealer seemed to know the sellers were suspicious. When I called, I described possibly what the criminals looked like, and what cards they had. Dealers responses "Seemed strange", "they didnt know what they had" "they had different stories" etc. Not many people walk around with 500+ 1952 topps in great shape. Sure enough ONE dealer eventually bought them. It taught me almost everyone has their price..among other things. Thieves are the lowest form of life..unless you are a bank robber the banks are insured
