Was the July spike a result of a rising tide or just a few cards spiking in price? - maybe due to some stiff competition in a bidding war or a couple of new investors entering the market.

Many of these players have passed away already, but it would be interesting to track individual stocks (cards) and see if there is data to show correlation between the prices and certain events. For example a player's death, or election to the Hall of Fame or if they are 'trending' in Google searches. One might imagine that Roger Maris's cards received more interest when McGwire was chasing his record or Hank when Bonds was chasing the all-time HR record. Or Bench, Mays, Koufax and Aaron when they were named the greatest living ballplayers in 2015.

Lots of data here to be analyzed - and to learn from.

And even though this is historical data, what would your curve have looked like if you had attempted to draw it before looking at the data? No absolute values, just trends. Was the hobby aware of the July spike and how things were climbing before that and how they've decreased since?
