I can't determine the other "sales", one seems to be a broker that was returned and I haven't been able to find a trace for the other one.

Closing, as I've decided to cash out a chunk of my BP and this hat isn't free of that. By extension, there may be sales in the near future which will impact the price. If somebody else wants to take this suggestion though, it's all yours.
