Bobby BinderThe data we store stays forever in our system or at least the price, date and auction house. The link to the auction dies out over time and we are working on ways around this factor. We do not have a set tabulation function yet but will be able to install something down the road. This way you can see how a set as a whole is performing over time.
I just went through basically every card in the set and with our new graph feature it was a downward arrow on practically every card in the set. Looking at the sales frequency shows it has greatly curtailed from 18 months ago. When we first started tracking data the 33 Goudey's where not far behind the T206's.
