Thanks for looking into this so far.

The Dayjogger was purchased from Stn for 41 keys

There are a couple sales on the Sylicone Succiduous Hazard Handler.

https://backpack.tf/profiles/76561199059632349#!/compare/1706054400/1706140800 - Sold for a Green Energy Executioner (76) + 5 keys = 81 keys

https://marketplace.tf/items/tf2/31374;5;u287

$99.99 / $1.71 = 58 keys

Sales on the Executioner:

https://backpack.tf/profiles/76561198125791160#!/compare/1703808000/1703894400 - Sold for 76 keys (Near ID: 13985656521)

https://marketplace.tf/items/tf2/921;5;u9

$179.99 / $1.70 = 106 keys

106 seems high compared to buyers. 76 seems fine as a mini here.

So the Sylicone Succiduous Hazard Handler has 2 sales: 58 and 81. The mid-point is 69.5 keys.

Also, the Eerie Kraken Bottle Cap should be fine since it is a small part of the trade.

So the Harvest Moon Safe'n'Sound sale is:

https://backpack.tf/profiles/76561198063179541#!/compare/1707782400/1707868800 - Sold for a Global Clusters Hazard Handler (80) + a Sylicone Succiduous Hazard Handler (69.5) + a Arachne's Web Dayjogger (41) + a Jellyfish Field Close Quarters Cover (44) + a Haunted Kraken Airdog (35.5) + a Sylicone Succiduous Close Quarters Cover (142.5) + a Eerie Kraken Bottle Cap (80) + 105 keys = 597.5 keys

597.5 would round to 600.

So this can be 500 - 600 :D
