Are you sure it was 332, because that is an odd number of keys to sell at. The compare links aren't prefect, you can always add and ask the seller and/or buyer to verify.

Also there were several SCM sales that took place within the dates (2nd - 3rd). 2 for a lot and several for really low. It is likely a safe bet that one of those high ones ($638.20 & $649.99) was your Sale 1. Both of those come out to around 275 - 280 which is strong evidence for your low end. You can also add that guy and ask him what he paid too for further evidence. :)
