SCM - https://steamcommunity.com/market/listings/440/Unusual%20Taunt%3A%20Battin%27%20a%20Thousand%20Unusualifier Sellers from 3.31€ (~1.7 keys), buyers at 2.41€ (~1.2 keys)

5 is definitely an outlier since it's far apart from the other sales and also has much less volume. 1.15-1.35 seems a bit low but keeping 1.4 and 1.45 in the range since it's still a fairly common trading point and there's only a single buyer at ~1.4 and another at ~1.45 (choosing 1.4 instead of 1.45 keeps the range slightly neater). One seller at 1.55 isn't enough to counter lots of sales so including 2.2 in the range and going with 1.4-2.2 keys
