Three recent sales, one of which was a bulk trade (logo set): http://www.tf2outpost.com/trade/15636847 and http://www.tf2outpost.com/trade/15636809 (note that the new owners on all of these hats are McDerpinBurger). Really hard to track down a price for only this hat since it's part of a collection, so I'll leave that out.

Before that, this Batter was part of a collection again; see here: http://www.tf2outpost.com/trade/14965447 so it is again hard to put a price on an individual hat on a collection. Everything else is way too far back to use as a data point.

Here is the other Logo Batter: http://www.tf2outpost.com/trade/14718762 no sale, and I can't track down the sale that let this guy own it.

Looking at noteworthy recent offers on the Batter:

Bubbling Cannonball + 1 key. Bubbling Cannonball was last suggested and accept at 1.4-1.5 buds, taking low price *0.9 = 1.26 buds, add in the key makes 1.3 buds => ~24.7 => 25 keys approximate value, rejected--however, this is in Unusuals, so maybe he preferred to keep the Logo Batter instead of trying to sell the Cannonball.

1 bud + White Bills for the Logo Batter => 2 weeks ago, Buds were ~16 keys. Bill's hat is 6 keys, plus White Paint = 50% of 2 keys => 7 keys value, 16 + 7 = 23 keys pure, rejected because he was already offered 25 keys, which was stretched to 26 keys then retracted. This is the highest pure offer so far, although it was made a month ago (so a bit dubious). Therefore, 26 keys is the high range that I suggest, as no other offers go above 26 keys.

Going back even further, another offer of 24 keys was offered but rejected. This still fits in our price range.

Now, onto the two recent sales...

1. http://www.tf2outpost.com/trade/15656495 (Sold for 25 keys, that was easy!)

2. http://www.tf2outpost.com/trade/15958826 ("Quickselling" for 20 keys after failing to get ~1.5 buds for it. If you check the BP history between 11-24 and 11-25, you see that he gained 18 keys and about 2 keys worth in items/metal, so 20 keys was a sale). http://backpack.tf/id/stfudonnie/

The current trade open: http://www.tf2outpost.com/trade/15963623 (nothing noteworthy)

All in all, I put 20 keys as the low range because that is what this Hat sold at recently; not sure if you guys would call it a Quicksell or not, let me know what you think and what I should re-suggest at if you disagree with my low range). High range is 26, I'm also a bit dubious on that since TECHNICALLY 1 month ago there was a 26 key offer so I had to put that as the high range, but the recent sale was at 25...so maybe the high range should be 25 instead?

Either way, this hat needs a refresh in price, the last update was 7 months ago...way too long ago. 20-26 is what I suggest, let me know if you think there is a better range as I'm not 100% sure that my range is the best considering 20 keys "could" be called a quicksell, and I'm not sure if a 26 key offer made 1 month ago still really counts (and it was rejected too, but no other higher offers, and a recent sale at 25 keys suggests that about 25-26 keys is the highest the hat is going to get).
