(Amended suggestion with proper minis. Shoutout to Explocivo808 for helping me with this!)

Traded July 30th: https://backpack.tf/item/11387615246

Personally bought for a non-strange BF Thousand Yard(235) + $280 via PayPal(280/1.5 = ~186) = 421

Total trade value was 421, but because the B/O was listed at 400, I am suggesting 400.

Price Points: 1.43, 1.46, 1.47, 1.49, 1.51, 1.56

Excluding 1.43 for lack of sales and including 1.56 for a healthy amount, I think a range of 1.46-1.56 is acceptable, using a median of 1.50.
