Teeny, D0, Icy have all priced this. I must carry on the tradition.

Explo appeared to think this sale was higher, by taking #sold-items screenshot, but that has never been an acceptable thing for suggestions and even admitted by staff of liquid that it's inaccurate. https://i.imgur.com/thBoYZe.png

According to Explo, out of the 18 keys matched which I checked, only one of them matches, and them being a price mod they concluded that this sale must be 18 even though only 1 key matches, so I will use that here.

Sales @ 16, 18
