Won't use this sale to set the range but will use it as support

March 20: $99.99/2.19=45.66 ~45 keys

April 25: $99.99/2.01=49.75 ~50 keys

Unsolds:

Marketplace.tf at ~50 keys, been there for over a month https://marketplace.tf/items/tf2/463;5;u3052 https://backpack.tf/item/9572757783

50 keys for 17 days https://backpack.tf/item/2547269800

Sales at 25, 30, 30, 45, 50.

45 and 50 are no doubt outliers, they're Marketplace.tf sales really far away from the pure sales. The fact the seller at 50 has been there for over a month explains it all too

Going with 25-30 here
