You need sales. :)

You will need to actually use this item's recent sales to update its price.

You'll need to look further into those sales to find additional sales for items involved without a price or with outdated prices, but this is a starting point.

This suggestion should be closed until those sales are looked into.

besides what's been said, for your edification -> https://forums.backpack.tf/topic/6033-rules-for-unusual-price-suggestions/

I suggest you close this before a mod does. If you need help with suggesting you can join the bp.tf discord
