Anyone have a reason for this price jump?

I was thinking of going after an '09 Glavine sweet spot auto, but look at this jump from previous sales:

What is going on here? anomaly? I'd love to get one of these for 15-20, but I'm laying off if they go up that much.

Nope, doesn't make sense. Actually, it would make sense if it was me that either sold one of the lower ending cards or if I was intending to buy one and the price would triple in price for me to win it.
