Sold for an indate Magnetic Hat Protector effected Universal Translator + Bill's Hat = 20 keys

So we have sales at 15 keys and 15 refs , 16 keys , and 20 keys, I'm rounding the 15 keys and 15 refs to 15 keys since keys are 34.44-34.55, but many of them are sale at 35 refs and even counting with 34.44, 34.44/15= ~0.43 so I had to round it down.

Range: 15-20 keys

Also thanks a lot for Lemon and Foamy for helping!
