I want my son to inherit my passion for the cards I collect but I surely will not force it on him. If, as he gets older, he has no interest, then I'll sell off and go on a nice vacation with the wife. If he has an interest, it's his.
However, I did get a kick out him wanting one of my cards as I was dissolving my modern stuff. He chose a '93 UD SP Kevin Reimer and made sure it was at his spot next to his plate at the dinner table for about a week. I was going to keep that card but then the wife tossed it the other day.
