Add graph for value growth or 'capital gains' of collection
Currently the graph displaying the value of your collection over time includes new additions to your collection as increases in value to your collection
My suggestion is to have an optional graph which shows the growth in value of your current collection over time, letting you see how much your current collection was worth x years ago as if you had always owned the collection.

separate genesis by model's and also dont allow mini systems and newer models to affect price of original.
right now it shows all kinds of crap mini systems and model 2 and 3 mixed in with model 1. Same with snes and nes. Also its showing less expensive variants like the sega gt/jsrf combo mixed with the good jsrf. Then also regular xbox version or peter jacksons king kong driving down the price of the 360 version.
