Strange quality items suddenly droppped in price in my backpack

[Colonel Johnson]

Today i checked my tf2 backpack and noticed that all my australiums plus other strange quality weapons have a way lower value even if no price suggestions have been made about them. For example, my strange professional Batsaber that was 42 keys yesterday, now is 29 keys, but the value on the site is still the same and even the buy/sell orders didn't change looking at the related price

Like with skinned items, killstreak items are valued based off of SCM sales. If there are no recent sales, the price defaults to the value of the base item (i.e. no killstreaker), which gets priced via suggestions.

 

As one just sold on the 24th, it now has that value assigned to it.

Backpack.tf somehow priced keys at $3.44 on scm (I have no idea how you even manage to do that). Killstreak prices are based off of the scm price of that item divided by the key price ($3.44).

 

So a $100 item that used to be 100/2.5 = 40 keys is now 100/3.44 =~29 keys
