Since the compare links do not show the 4 keys, you will need to take a screenshot of your trade history to show the keys were indeed traded (also there are more sales earlier in the same history https://backpack.tf/item/7495263352).
which means you are correct in valuing your sale at 14 keys (my bad)
But the point still stands that both sales are quite discrepant.
Now, it's very possible the 8 key sale could be low, but we have no way of determining if this is the case unless you have further evidence.
tl;dr I wouldn't be comfortable pricing off of your purchase alone atm without further evidence
You could price at 8.1 - 14 keys here but imo that would be quite wide
(The other concern I would have is your sale is Pro KS, which we may expect to add some value, and the sale being higher potentially supports that assertion)
I feel like it should also be noted that the unused war paint in strange FN has sold five times on mptf for 39.99 in the last 3 months:
This is fairly high, though, given the key prices were anywhere from 1.83 to 2.01 USD, this is roughly 20-22 keys. Sellers on backpack are usually at 18-19 keys.
given the other sale provided, 8 - 14 would be better here

COMPARE DOES NOT SHOW 4 KEYS PURE INCLUDED IN TRADE
Traded for a strange field tested broken record WP (~16 keys) and four keys pure.
in this trade, the broken record paint was considered around a key above current buy order price (~10 keys)
https://backpack.tf/stats/Strange/Broken%20Record%20%7C%20War%20Paint%20(Field-Tested)/Tradable/Craftable
~10 keys + 4 keys
= 14 keys

Recent Spec KS sale here too:

Preferably a mini for the Broken Record Paint could be made as well - valuing 'around' buy order price seems a bit vague here.
Should I make a new price suggestion or just list everything here?
Here's the screenshot of the trade with the four keys:

SCM (USD) sales @:
- 27.63
- 23.00
- 45.63
- 46.59
- 46.00
- 38.04
- 39.66
- 34.52

Key price on SCM at the time: 2.36
- 23.00/2.36 = 9.75
- 46.59/1.36 = 19.75
Assuming the 23$ sale was scm buy order.
1 sale on mptf on June 17 (key price at time was 1.99) for 30.03
- 30.03/1.99 = 15.1
The evidence for your purchase should be good here.
However, I think an important thing to consider here is this SCM sale on Aug 3: https://steamcommunity.com/market/listings/440/Strange%20Specialized%20Killstreak%20Star%20Crossed%20Revolver%20%28Factory%20New%29 for ~8.08 keys, which is much lower than your sale.
Edit: I found the 14 key buyout for your purchase https://next.backpack.tf/classifieds/snapshots/Strange%20Professional%20Killstreak%20Star%20Crossed%20Revolver%20%28Factory%20New%29/68b005ef44ca071f3b0e1994

Closing due to lack of response.
