At the last card show here in SYD, I was sitting with Sonny and this older guy came up with a folder of NBA cards from 93-94-95, mostly base. He said he had put them away from his son years ago hoping to hold onto them and see how much they're worth now. It was a nice story but it wasn't easy telling him that they're worth pretty much nothing. He took it well though.
It just shows that there's alot of people out there that aren't as 'educated' as we are and that we shouldn't dump on them. If they react harshly, and I've had the same situation Scotty after trying to explain to someone about what their cards were worth, then it's their loss.
