Looking at the data in the graph of medallion prices is very interesting. They do chart the main line and the 60 day moving average, but it looks like there's an interesting secondary trend in the data, where there's another line of sales that looks fairly contiguous but is lighter which seems to be about 25% or maybe 33% of the higher line. Also it looks like there are some higher lines that look stair-step (probably using round numbers for the prices). I wonder if these are other sellers or groups, but it seems like the lower line might be the actual value of a medallion in a not ridiculous price inflation way?
