Sale 2

51.40 october 9th 2025 (keys valued at 1.89)

27.1958 keys

2 other sales go really high and are considered to be outliers and out of range for the time they happened.

Hopefully this now reflects the price range better, with a justification for the value on the Brolly for the value of sale 1. Making this range hopefully justified.

Currently looking to add more sales if found by anyone please comment to add.
