The Motif has no Mini, but this sale supports a drop.

138 + 138 - 46.5 = 229.5, which rounds to 230 Keys

https://imgur.com/a/vYCborQ - The Bonk/Scatter/Pistol/Greased sale is capped by the Buyout of 140 Keys

Since 106 is on the older side compared to 136 and 140, I'll call 106 Keys low.

Sale 9) Sold for a Sunbeams Shellmet (75 Keys) + 45 Keys + Circling TF Logo Towering Pillar of Hats (31.4 Keys) + Cloud 9 Screamin' Eagle (25 Keys)

https://backpack.tf/profiles/76561198269636307#!/compare/1564963200/1565049600

75 + 45 + 31.4 + 25 = 176.4, which I'll round to 175 Keys since the Pillar Mini is likely a bit high.
