Unpriced! 1 seller on bp but the "sale" i believe is just a transfer. (Did check anyway, if it is a sale, its untraceable)

However, plenty of marketplace sales! --> https://marketplace.tf/items/tf2/31091;5;u33

May 7th -> 40 / 1.88 = 21.27k (~21k)

July 9th -> 30 / 1.99 = 15.07k (~15k)

July 15th -> 25 / 1.99 = 12.56k (~13k)

July 21st -> 30 / 1.95 = 15.38k (~15k)

Sales ranging from 13 - 21k - 13k sale is obviously a qs.

Taking a price range of 15-21k!
