2011 Topps Update Mike Trout went from $20 or so to $2,000 (100x movement) or so during a ten year stretch that ended quite recently.

PSA 10s go for about $1,500 right now. In December of 2012, Trout was about $50. 30x movement compared to this date 10 years ago.

For anyone who is about to write, "well, Ack-shoo-uh-lee, that's not an apples to apples..."

Just stop. in 2012, the Trout was a base card from a one-year-old product. You could have picked up gem mint raw cards all day long.
