Suggestion: Sulphurous German Gonzila at 25–32 keys

Low of 25 (lower than cheaper and more common effects like Disco and Phosphorous) seems a bit of a stretch as it is based on a duped item. But regardless:

The skinned sniper rifle was sold for 6 keys to sa1tz BuysBackpacks/ReadProfile. https://backpack.tf/profiles/76561198292156436#!/compare/1500249600/1500422400

Plus the 1.6 keys of the Earbuds = 7.6 Keys

So 35 - 7.6 = 27.4 Keys for the low (still based on duped item where price can fluctuate a lot)

For the high, should it not be based on the sale value at the time of the Puzzle Hellmet or value now (not an opinion of what the value of the other item should be)?

Sale for 7 pure for Rifle

And as you linked, sale @6 is correct here.

That makes it 6.5 key + buds (1.6) = ~8 keys

Berliner's is 32-35 keys = 33.5

33.5 - 8 = 25.5 rounding to 26.

Was rounded to 25 tho

And not, value of hats should not be based what they were. We use actual price or if it's outdated price we use minis.

Okay thanks, I am not experienced at pricing. I just thought it weird as well that hat can be priced based on duped one as the value of duped can fluctuate a lot as some people don't like duped, but others do not mind at all. Like you also commented:

Berliner's traded for 56.5 key hat?

Anyways, I will probably won't sell anytime soon (if ever) :) And the others with this hat seems to be inactive tf2 accounts and/or duped. So this will just be a nice boost to my backpack value.
