The last few days at the shop have been reminiscent of a marathon of Pawn Stars. Quite a few people have come in wanting to trade for store credit. Most of them have left disappointed. We did pick up a few things here and there (which hopefully I can sell.)
The problem, in a nutshell, is that people get it in their head that a (YuGiOh) card is worth X amount because they looked it up 2-3 years a...go, or someone told them it was valuable... then they play it in their deck for a year without sleeves, and cram it in a binder covered in duct tape.
By the time they bring the cards in to me, new sets have come out which often de-value the tournament usefulness of the card from $20 to *maybe* 50 cents, in mint condition.
Which means I can offer them about 10-15 cents... only they are almost never in mint condition, which means I usually offer them nothing at all.
Most of the time, you can watch their smile fade as I start going through their cards. It's kinda sad, really, since I know they think they've spent the last two years walking around with the keys to their own personal gold mine.
I don't really enjoy seeing that look on a child's face. I like kids and I remember those moments when perception and reality crashed headlong into each other. It was seldom pretty. So, when I'm talking to a child, I try to take it easy on them and give them some suggestions on how to better preserve their cards.
Sometimes though, it's an adult. Depending on the situation, my response to them varies pretty broadly. Most of the time though, I still feel pretty bad when it doesn't go their way.
