I did a little experiment with this round of Baseball Card Price Guide History. Harmon Killebrew passed away last week, so I wanted to compare his sales on Ebay for the week before his death with the week after his death. Anyway, here is Killebrew's Topps rookie card priced through history.

I don't have any pricing between 1987 and 1995 but the card did go up a good bit during that time. As with most vintage cards the pricing for them has gone down since the mid 1990s. However, this card has seemed to hold some value. As I anticipated the week after Harmon Killebrew's death there were more sales of his cards, however there was not an increase in price (which I did not expect). However, with the laws of supply and demand it appears more people probably put his card up for sale after his death. (Thus flooding the market to keep up with increased demand).
